Masonry blocks and bricks: comparison and using

In this article you will learn all the basic criteria and factors that influence the choice of a particular type of brick for the construction of walls. It examines all the major pros and cons of both types of walls.

Even just a novice builder or developer, never tight not faced with building materials, looking at the summary table which describes all the characteristics of the building blocks will be able to answer the question easily: "What, in the final account better unit or brick?".

All this will make their own decisions and to give preference to the best option.

Requirements imposed by the walls of houses

Regardless of what materials are used for construction of the wall of a residential building, or what it designs and shapes, is obliged to combine the implementation of some mandatory to perform the functions and requirements.

Structural strength

In most cases the building walls is the main element of it, which is acting to ensure the strength of the entire structure of the building.

Within a few decades, building walls should not have any problems to keep the load of its own weight, the weight of the roof and floor slabs, communications, as well as all the furniture and other interior filling apartments.

Despite the fact that in the central regions of Ukraine seismic activity is not too high, the echoes occurring at remote distances earthquakes sometimes reach up to us. So, margin of seismic stability is a must.

Since all of the materials for the construction of the wall is mainly exposed to compression load, this is the most significant criterion is to choose a brick. It is called "mark" or "grade strength" that is often used in building material name.

In real life, the strength is often expressed by means of a system of calculation, but enough to know one simple rule: 10MPa equals (approximately) 100 kilograms per square centimeter.

In other words, if you bought a block wall material, whose compression strength is equal to 12.5 MPa, it can not worry since it is constructed of a wall that has the same strength if built of bricks brand M125.

On every square millimeter of cross-sectional walls, can easily be applied load of 12.5 kilograms and it will not bring any damage or other consequences.

In the real world of construction, the materials on the compressive strength is less than 10 kilograms per square centimeter is not used for constructive purposes.

The maximum level of safety for the individual materials is caused by the number of floors of the building under construction. If conventional built house or a private home, the maximum strength brick or block mark strength more than 150 kg per 1 square centimeter is redundant.

Reducing the load on the foundation

If we neglect minimizing load on the foundation, it can cause unnecessary rise in the cost of the ground floor of the building, or, on the contrary, lead to the destruction of the entire structure that is a disaster.

From school physics course we all know that the weight of any natural material depends on such parameter as the inherent density of the material.

During the analysis of various options for the device wall structures, we can face such kinds of materials that have a large void content (Which provides technological feature of the material), so that, for comparison purposes, we will use this parameter as the volumetric weight or average density.

This parameter is measured in kilograms per cubic meter and reflects what the mass of material per one cubic meter of brick or block.

Resistance to heat transfer

Everything is not so difficult. This parameter indicates for how many degrees will fall or rise temperature wall surface (heat-stabilized at room mode) whose thickness is 1 m, in the case where the outer wall surface to install a heat source capacity 1Vatt.

When comparing the thermal properties of various materials need to be aware that the lower the value the thermal conductivity, the better insulating properties has chosen material.

A comfortable room temperature can be achieved only when comply with the minimum possible value of the thermal resistance of the building walls.

Thermal resistance depends on the wall thickness and thermal conductivity of the material from which it is constructed. To him the value provided at the rates which are set out in the DBN V.2.6-31: 2006, depending on the temperature zone of Ukraine, one of which is the building.

For central regions (Zone 1 and 2), this parameter is 2.8 and 2.5 m2 * K / W, respectively.

water absorption

Various materials for the construction of walls in different ways exert their properties by reacting with atmospheric precipitation. The main indicators of their interaction are the ability to retain or absorb moisture.

Water absorption is calculated in a numerical percentage water mass, which is able to absorb a particular material for the construction of walls at its full saturation, by weight of dry matter.

Larger values of water absorption indicates a deterioration in the properties of the walls when wet. All this may lead to a decrease in thermal resistance, an increase in the average density, decrease the overall strength, sharp deterioration microclimate conditions smokers.

The value of water absorption for more parts of bricks or building blocks is between 6 and 15 percent.

So, when choosing the material guided by a lower water absorption, otherwise, the operation of such wall will become a problem without the provided additional protection from moisture.

fire resistance

It is necessary to consider only those types of building blocks, which are entirely made of fire-resistant materials are not subject to combustion.

frost-resistance

The worst damage to the facade of the building causes the cyclical repetition: freeze moistened sections of the wall and subsequent thawing.

A well-known fact that water during freezing increases the volume, thereby forcing particulate material. After a few of these repeated cycles, the material significantly loses its strength properties, to the extent that it will crack.

Parameter frost resistance of the material shows the wall elements to continuous freezing and thawing.

It is characterized by the number of freezing-thawing cycles, which are guaranteed to be sustained without falling material strength and significant manifestations destruction.

Modern wall materials have frost calculated from 25 to 35 cycles. All of those materials are less frost than 15 cycles, are not suitable for use as a primary materials for walls and require mandatory presence of protection on the front side of the building against penetration moisture.

How to Choose a material for building walls

To finally decide on the choice of material for the construction of the walls, not enough to choose the most suitable in terms of technical and operational properties of material that satisfies all of the above requirements.

The following are further criteria that affect our final decision.

cost of

Very often it is the solvency of the person is the decisive criterion in the selection of the material from which in the future will be built a wall of his house.

It should be borne in mind that the final cost of the entire "box" affect direct and indirect costs as a whole.

Direct costs - the cost of the material itself, the cost of cement mortar or adhesive for laying, as well as payment for services of builders erecting the structure.

Indirect costs - these are the tools that are on the organizational issues of warehousing and storage of materials, transporting them to the worksite as gradual construction of the wall, as well as preventive maintenance measures stipulated regulations throughout the subsequent lifetime walls.

Many of the materials and design features are not able to provide the entire set of desired characteristics of the walls. In these cases it is necessary to take into account also the cost of works by additional thermal insulation space, the cost of building materials and direct their assembly.

There may be situations in which the developer in the pursuit of more "interesting" in his view price proposals decides to build the walls of these wall materials, which are in operation in the near future will require replacement of some components or cosmetic repair.

So in the design of their future housing need to treat it as a living organism, which will have to stand for more than a decade.

Any house of any whatsoever material is safe from all kinds of "diseases" and aging over time. So it would be better if you have a very early stage and minimize disturb all of its costs and future efforts.

The pace of construction

In some cases, the speed and the pace of construction may be the most important requirement to the entire construction process.

Imagine the situation: the calendar shows a warm summer month of August, and you have only built the zero floor.

Where prior to the middle of winter you do not do though, would "box" building and close the roof of the house, you run the risk of losing the opportunity to proceed to finishing work without looking at the calendar. But this is not the worst thing would be much worse if the frost and snow will affect the technical equipment and finish your building.

On the walls of the building designs

The wall of the brick (ceramic).

It is the oldest, but repeatedly-proven method of building walls.

Ceramic bricks made due to firing sorted and unfolded forms of clay preform.

At this point, for the erection of walls used conventional hollow standard brick size 25h12h6,5 cm or "sesquihydrate" - 25,9h12h8,8 cm.

Characteristics:

Weight - 2.4... 2.7 kg
Compression strength - 125 kg / cm2
The averaged density - 1350 kg / m3
Thermal conductivity - 0.4W / (m * K)
Water absorption - 13%
Frost resistance - 35 cycles

For masonry used solution from the hard cement-sand mixture. The thickness of the seam between the bricks ranges from 8-10 mm.

The thermal resistance of the solution is much less than that of building brick. Multiple sutures are a kind of "cold bridges", so that in real terms, the walls of ceramic bricks have a much poorer thermal characteristics.

Due to the fact that these walls have high strength characteristics, they are difficult to drill and Stroebe, for the purpose of laying utilities or electrical wires, so that even a slight deviation from the envisaged project placement laying tracks locations of all communications, can present a lot of trouble in the future with electric instruments.

It is also important to know that the inner surface of the wall of the brick is not perfect. It always requires additional finishing.

Quite a high price for the construction of one cubic meter of finished designs due to the need use of a large (in average of about 20 per cent of the entire wall) the amount of solution for laying, as well as the complexity and high manufacturing labor intensiveness process.

On average, one standard hollow ceramic bricks stands in the district X rubles apiece. For the erection of one cubic meter of the wall is necessary to spend 394 pieces of the brick, which will cost approximately XX rubles.

In turn, the solution costs more than X rubles and still need to pay workers more about X rubles.

Ultimately, the cost of one cubic meter of a wall of ceramic bricks will be more than X rubles.

On the benefits of the walls made of ceramic bricks

The main advantages of such a wall - is a high strength and load capacity design. Laying of ceramic bricks is able without any supporting activities to strengthen the load-bearing capacity of rafters and plates inserted floors.
In addition, it is ecologically clean and is resistant to any biological effects have been burnt clay clay has a high biological inertness.
Due to the sufficiently high thermal inertia markedly reduced dependence tenants of red bricks from sudden changes in air temperature outdoors.
Geometric and operational characteristics can persist for 100 years or more.
The high level of resistance to fire
Due to the small overall size of the brick, it is possible to carry out quite complex structures with small radii of curvature. There is no need to machine the wall.
Easily compatible with many types of additional internal or external finishes, which can be: stucco, siding trim, facing bricks or any other protective panels with the element decor.

On the shortcomings of the walls made of ceramic bricks

Increased requirements to the foundation because of the increased density averaged finished construction of such bricks, which provides a lot of weight wall.
It requires the use of specially designed grid-spacers, because of the plurality of voids in brick unit, to prevent the possible wicking of cement slurry in these voids.
Due to the low thermal resistance is required either to construct a large wall thickness is sufficient (from meters and larger) to ensure the thermal comfort of the premises, or use the auxiliary materials for thermal insulation premises.
Due to the small size of the bricks there are additional large time and monetary costs of construction. According to current standards, the rate of production of the builder during rough construction of the brick wall is approximately 1 cubic meter for 8 hours.
Maintain the following set of all possible details and parts. For example, the constant monitoring that the walls were vertical or proper organization and quality bandaging brick rows. With all of this in a position to handle an experienced developer, but not a novice.
When standard thermal characteristics provide a high cost per square meter of wall.

Brick wall of silicate bricks

For the production of silica brick used lime, sand and a minor amount of additives.

Special forms packaged silicate mixture is reacted with hot water vapor, which acts on the pressure 10 atmospheres.

The size of sand-lime brick is similar to the ceramic, so in actual construction, they are interchangeable.

Advantageously, the calcium silicate bricks manufactured and conforms to the following specifications.

Characteristics:

Weight - 3.7 kg
Compression strength - 150 kg / cm2
The averaged density - 1750 kg / m3
Thermal conductivity - 0.95 W / (m * K)
Water absorption - 13%
Frost resistance - 35 cycles

During the construction of the Seine from the sand-lime brick, any additional materials, method of laying, as well as the cost of the same services as if with ceramic bricks.

Note, however, that the bricks can not be used for the construction of walls that may constant hydration, which are baths, saunas, swimming pools, basements.

It is also necessary to avoid the direct contact of the silica brick walls with chimneys and other elements with high temperature, in view of a possible thermal degradation of silica brick.

Because of similar size and silicate ceramic bricks and similar recommended thickness stacker seam, their average expense for the construction of one cubic meter of the wall will be similar.

Due to the fact that the lime stone is cheaper than its red counterpart, total cash costs will be less. The average cost of a silicate brick is within X rubles apiece.

For the erection of one cubic meter wall will need 394 units of bricks that will be in the amount of X rubles. Also, included in the cost for the construction of a cement slurry walls - even X rubles and pay construction workers, additional X rubles.

Thus, the total cost of one cubic meter of sand-lime brick wall will be about X rubles.

Winning almost 25% of the cost of materials. However, these savings can "come to nothing" because of the fact that the sand-lime brick is characterized by very weak thermal resistance and high demands on the strength of the building foundation, you'll need to increase the thickness of the wall that will cause more consumption material.

One cubic meter of wall made of silicate brick weighs 400 kilograms more than the walls of a ceramic stone.

On the advantages of "silicate" wall

High strength and load-bearing characteristics. Masonry of silica brick capable without the use of auxiliary measures to counteract the load of the truss system and floor slab.
Resistance to biological effects and environmental quality. Lime and sand are sufficiently inert in terms of biological materials.
Saving geometric and operational characteristics for a very long period.
The high degree of fire resistance
Due to the small size of the brick can build very complex in terms of constructive elements with small radii of curvature, without requiring further mechanical finishing.
Easily combined with the majority of additional finishing materials - facing brick, siding, stucco and other protective panels with decorative elements.

On the shortcomings of "silicate wall"

Increased demands on the foundation of the building because of the heavy weight of the wall, which is due to a sufficiently large average density of masonry.
Very weak thermal insulation properties of silicate bricks need to provide for the organization thermal insulation of buildings, or the construction of a thick wall that is irrational in economic plan.
Due to the small dimensions should be an increase in time and financial resources for the construction of the wall. Normal production rate is similar for laying ceramic bricks.
It is not recommended to use lime for the building facade brick, because of the impact of rainfall sand-lime due to the passage of time are destroyed and weathered. Also, in large cities and near industrial facilities, bright white houses made of silicate bricks turn gray after a few years.
When erecting the walls of the silica brick is required to provide a plurality of various components such as the organization correct bandaging rows of bricks, as well as continuous monitoring of the vertical position of the wall that is not so easy for beginner.
To ensure the required thermal performance uses a lot of bricks, which leads to an increase in the cost of one square meter of wall from silicate bricks.

Wall-based ceramic blocks

For their manufacture uses the same kind of clay as described above for the ceramic bricks. They are also similar in terms of production and technology.

Characteristics:

Weight - 18.6 kg
Compression strength - 128 kg / cm2
The averaged density - 830 kg / m3
Thermal conductivity - 0.21 W / (m * K)
Water absorption - 12%
Frost resistance - 50 cycles
Dimensions blocks 380h248h238mm
Equivalent bricks - 11.5 pc

The main difference between them lies in the fact that more than 50% of the unit volume occupied by the through-channels of small cross-sectional area, which are evenly distributed throughout the volume of the ceramic block. Furthermore, due to the channels on the outer surface of the block projections are provided, which provide a better grip blocks with each other and perform the function of a kind of lock.

During installation, the blocks in one row to each other, the blocks "are" one another, this is achieved at the expense of high-quality fixation ceramic blocks horizontally. Thus, the cement mortar used for laying, is applied only to bond with each other horizontal rows.

Typically, the ceramic block is a multiple of the size of bricks, due to this they are easy to fit in places with each other with complex geometric design, which usually requires amplification or combining block brickwork on the front wall building.

During the construction of the walls of large ceramic blocks with a large number of pores, the same applies for masonry mortar, as in the case with ceramic bricks. However, due to the fact that no need to fasten together the blocks vertically, it consumes less, which affects the economy.

Construction of the walls of these blocks can go 2.5 times faster than a brick, but wages remain the same construction workers.

However, you should pay attention to some pleasant moments, namely due to the low average density of the wall, you can take the zero floor is not so strong, that will save money; due to the high thermal resistance of the wall thickness can not be very large, and the thermal insulation space activities may not be necessary.

The cost of large-sized blocks for the construction of one cubic meter of the wall is approximately X rubles namely blocks and another for X rubles additionally for grout. Also make sure you need to pay the builders work, even X rubles.

In the end, we get X rubles per one cubic meter of wall. At a first glance it may seem that it is a lot, especially remembering the last calculations for the bricks. However, note that for the same strength characteristics, ceramic blocks have better thermal properties that allows you to make the walls thinner and provides less consumption material.

Thus, one cubic meter equivalent blocks in the wall is equal to two cubic meters of ceramic brick or more than three cubic meters of silica brick. That is, they are large enough X rubles are becoming quite affordable X rubles.

Important. The surface of the block which forms the front and inner surfaces generally have a small corrugation, thereby increasing the grip and wall finishing materials.

Despite the fact that many manufacturing plants of large blocks do not talk about the need for a reinforced belt because of high strength blocks (similar to ceramic bricks), the final decision events to strengthen places where the walls lean window / door lintel plate and floors, should be taken back in the course of a project, taking into account all the nuances of construction, such as the type of roof, the size of the overlap spans and so on.

On the advantages of large-size ceramic blocks

High strength and load-bearing walls abilities similar masonry
Resistance to any biological effects: use the same type of clay, as well as for ceramic bricks and is inert in biological terms.
Due to the high thermal inertia, is reduced in dependence of the occupants of the building blocks of ceramic abrupt change of temperature outside.
Due to the good thermal characteristics are required the cost of additional thermal insulation of buildings
Geometric and operational specifications are stored for a sufficiently long period
High resistance to fire
Lightweight and easy to install
Low consumption of cement mortar for masonry
Low cost per square meter to meet certain thermal parameters
Large wall construction speed (2.5 times faster than a brick)
Easy to match with most finishing materials: plaster, protective panels, siding and facing bricks.

Disadvantages of the walls of large blocks

Due to the presence of voids provided by technological characteristics, it requires the use of nets, spacers which will prevent the cement from flowing solution in these voids.
Since the structure is non-uniform blocks, when pruned technological voids are open under the desired size for which require additional measures to strengthen the data slices, or binding of all sizes to the standard block size.
Due to the fact that such units are brittle due to the large number of cavities, problems may occur when mounting to the wall of the various elements of decor or home appliances.

Aerated concrete blocks and a wall of them

The rapid development of aerated concrete production technology, in particular concrete blocks, once again confirms the known many saying "everything new is well forgotten old".

In the former USSR, invented more than a hundred years ago, aerated concrete, which is used for the construction of walls and successfully replaces the traditional brick, experiencing a second coming.

Aerated concrete is considered to be artificial stone obtained, which on the whole volume uniformly distributed spherical pores whose diameter reaches from 1 to 3 millimeters.

Characteristics

Mass block 300mm thick - 18.2 kg
Compression strength - from 15 to 30 kg / cm2
The averaged density - 400 kg / m3
The thermal conductivity in the dry state - 0.1 W / (m * K)
Absorption of water - more than 30%
Frost resistance - 25 cycles
Block sizes, 600h200h100... 400mm

Is made active form blocks similar method with the autoclave process for producing silica brick, but with one technological feature - apart from sand and lime in a mixture for producing aluminum powder is present block and Portland cement.

Due to the presence of aluminum in the mixture, and the air flow becomes easy in spite of all the other heavy components aerated.

Together with water, the aluminum powder is reacted with a solution gidrooksidnoy group, creating alumina (Which is the main component of any high quality clay) with hydrogen evolution, through which weight foams.

Together with these forms of calcium silicate (as in the time of manufacture of silica brick) and the individual components of portland cement hydration. The resulting material is ultimately not only contains all the best parameters of the materials included in it, but also gets two more other than additional parameters: a small averaged density at a large enough block of durability and excellent thermal quality material.

If you follow all the technological requirements and Literacy Project, a house of concrete blocks may not need any additional thermal insulation protection of the building.

The basis for the shape of concrete blocks are size 600h200 millimeters in length and height and width of blocks depends on the specific design requirements.

Maximum deviations in size do not exceed two millimeters in length unit and 1 millimeter in height and thickness, due to the fact that the aerated concrete blocks are subjected to strict control over geometric characteristics.

Due to these small variations, the blocks can not be mounted in cement mortar for masonry, and special small layer of adhesive.

Wall construction of technology resembles laying tile. The adhesive mixture is spread over the surface of the toothed comb glued blocks. Later, one block lies on the other and precisely fixed horizontally.

Such a small thickness of the mounting joint prevents formation of multiple "thermal bridges" and erected wall may be viewed as a uniform thermal environment.

Similarly to the case of application of large ceramic blocks, aerated concrete blocks are joined like a lock, which eliminates the need to attach them to each other along a vertical seam.

The cost of a dry mixture which is diluted and used for bonding between concrete blocks is approximately two times more than a conventional cement slurry. Cost of services construction workers are about the same as in the construction of the wall of the ceramic blocks.

Due to the very low density of aerated concrete wall, provided it possible to obtain even more savings in the construction of the basement of the building, as compared with the wall of the ceramic blocks.

On average, the market's leading manufacturers of aerated concrete costs about X rubles per square meter. adhesive solution cost for installation will be more X rubles. The cost of the work of builders will be in the region of X rubles.

As can be seen from the figures, the cost of building the walls of aerated concrete is about the same cost of the wall of the ceramic blocks.

However, this technology allows you to get more savings from ideal geometric sizes of concrete blocks that will help to minimize the cost of finishing.

If you follow all rules of installation, the resulting surface of the wall will not need a special alignment.

Another feature of the concrete blocks, which distinguishes them from all other types of bricks, is the availability of production, not only for the construction of block walls, but special additional elements that are used in the design of special nodes wall, e.g. webs, plates and floor coverings, insulation elements.

Well-designed structural features of these elements and methods of using them to perform a plurality of units and certain elements of the building, it allows, to the extent permitted, to simplify and speed up the installation work. For example, a small floor private house may be erected from the bottom to the top in less than one month.

According to data obtained from one of the manufacturers of concrete blocks for brickwork of walls square meter will require about 50 minutes time. This is the fastest and the best indicator of the rate of construction of all the materials for the construction of wall structures.

Very special attention, both at the stage of development of design documentation of the building, and in the process of its construction, will call for traditionally Presses structural elements and units - door and window lintel above the openings, supporting columns, the support plate seats on the intermediate floor bearing wall and so Further.

Despite the fact that the concrete block has a rather small strength characteristics for compression, conventional technologies used for brickwork unacceptable.

For example, if the traditional slab of reinforced concrete slab laid without preliminary preparation on the wall, built of aerated concrete, drawing on the principle of "in the fourth wall", the cooker can cut the blocks and design collapse.

On the advantages of aerated concrete wall

Resistance to any biological effects and ecological absolute. Aerated concrete obtained by autoclaved production sufficiently inert in biological terms.
The walls do not require additional insulating protection device, as aerated concrete blocks have a very high thermal resistance.
Geometric parameters and operating characteristics retain their properties for a long period of operation.
The high degree of fire stability.
Due to the isotropic structure, aerated easily attached machining - drilling, production channels for stacking the utilities and electric wires and sawing.
Simple and very convenient to carry out installation work.
Compliance with the accuracy of geometrical dimensions allow denial of rough facades and internal wall surfaces.
On mounting a small amount of adhesive solution stacking of concrete blocks requires. For 1 cubic meter of masonry requires approximately 20-25 kg of dry glue
Very high speed of erection of walls

Disadvantages walls built of aerated concrete

Aerated concrete blocks are highly hygroscopic, therefore, necessary to exercise special measures to protect the front side of the building from direct contact with atmospheric precipitation - rain or snow.
Not such a big strength values in comparison with all other kinds of bricks and blocks require the use of specially designed structural elements and the use of special technology installation.
To create a unique architectural shapes with complex geometry requires the use of a plurality of supporting elements, which are usually expensive, in comparison with the similar wall elements size.
To attach to the wall of concrete blocks large room decor elements, you must use special fasteners.

Summary information on all kinds of wall elements

The very first thing you should pay attention to looking at the above, it is the construction cost one square meter of wall made of these materials and the huge difference in speed performance of installation works.

The strongest material can be considered a calcium silicate bricks. However, the walls of the ceramic blocks and the ceramic bricks have not so small compression strength, so they can be easily used for the construction of small buildings, for example, low-rise buildings, private homes or cottages.

The smallest load on the foundation of the building blocks of aerated concrete have, but because of the weak strength properties of building walls, it is necessary to provide additional reinforcing measures, if you plan on building a house consisting of several floors and roof are going to do from the massive roof, such as ceramic tile to example.

The most optimal combination of the bearing capacity and the average density inherent brick walls constructed of ceramic blocks. They do not need to build a strong and solid foundation to withstand the weight of the structure, and the walls themselves easily withstand not only the reinforced concrete floor slab, but also a heavy tiled roof.

Among the thermal qualities of aerated concrete blocks, undoubtedly, lead and are unrivaled. However, the ceramic blocks behind much smaller than the silicate or ceramic bricks. Summarizing this point it should be noted that of thermal qualities, ceramic and aerated concrete blocks They are interconnected similar materials between which the customer can choose to build future warm home.

water absorption and hygroscopic large sand-lime brick necessarily require the implementation of a facade waterproofing measures. Although almost any material for the construction of the walls in need of a final processed facade material which is able to provide protection from the wet walls, avoiding their contact with atmospheric precipitation.

Of course, we can not say with certainty that all the above data with 100% accuracy indicate the best or the worst material for walls of residential buildings.

In each situation, each parameter can play a very important role and crucial in the end.

For instance:

For private homes, whose main task is to minimize the dependence on gas consumption or other energy, the best material that will provide the maximum heat-engineering quality of the blocks are aerated concrete.
Those houses, which consist of two or three floors, have overlapping spans more than six meters and covered with a heavy ceramic tiles as a roof, in the first turn, require high strength characteristics of the supporting structure, so that in this case the most preferable to use a fully (or partially) brick walls.
In cases where the house is built away from the manufacturers of aerated concrete blocks, ceramic blocks and ceramic bricks, preference may be given to the low cost of silica brick.
Those who want to quickly build a multi-storey private house is small in size, which would have good insulating properties and high strength characteristics, which would be sufficient for the construction of roofs of ceramic tiles, in this case the most preferable is to use a large ceramic blocks.

Parting words for thought

All of the above elements for the construction of the walls of the "pure" form are hardly used. The most rational yield in this situation is to combine the various construction materials such as ceramic bricks and ceramic blocks.

Those sections of the wall, which account for the bulk load of a building can be constructed from a large-size ceramic blocks or bricks. But those parts of the walls of buildings, which account for not too much of a load can be built of concrete blocks, which are very lightweight and have excellent insulation properties that safely affect thermal comfort future tenants.
