Brick-Lego - species, characteristics, application.

With the advent of various blocks of brick, though press from the leading position, but remained one of the most popular materials for the masonry load-bearing structures or as a facing page. When the mass of the merits of this material is demanding skills of performers, especially when it comes to the facade. Relatively recently, building materials market increased by Lego bricks, which is much easier to lay the classical virtue of characteristic shape, and gave it the name. As it turned out, among the participants there FORUMHOUSE and producers of this material and real users. They are willing to share the experience of how those people think about making homemade succumbed to the bright slogans and those who are attracted by the simplicity of the masonry.

Story brick constructor

The literal translation from English-Lego bricks (interlocking brick) denotes blockable brick or brick with a lock having a one side projections (spikes), and the other - the slots are in the process of laying reliably connected together without mortar thick seam.

"Father" of Lego can be considered as the Dane, Ole Kirk Christiansen, at the beginning of the last century, invented a brick with studs for fixing to simplify and speed up the laying.

Local architects and engineers appreciate the innovation, and in the late forties Lego was officially used in the construction of a public building, where they held a new way to "automatic on documents masonry. " However, patent an invention once the Danes either did not occur or did not consider it necessary, and when the castle brick has become popular in other countries, rushed, but it was too late. After several decades of trials in 2010. "parents" of bricks from Denmark was formally denied the right to be treated as such. Therefore, in the media from time to time flashed information about the students from America, the group of enthusiast from Brazil, but to their credit, rather to improve Christiansen invented the locking system.

Design features, the method of production, characteristics

Form standard Lego, rectangular protrusions and grooves are formed two circular cavities, the projection height is 5 mm as the depth of the groove and the diameter is 65 mm. By the size of Lego is close to the normal single brick, it has a standard length - 250 mm, a little more width - 125 mm, and the height varies between 65-70 mm, depending on the manufacturer. The weight of one brick ranges from 3 kg, which is due to the different raw materials.

Slot coupling system provides the primary fixation elements in the masonry, so there is no need for a thick seam, brick putting a thin layer or a glue mixture, extruded from a confectionery syringe type device or a special mounting foam. And in fact, and in another case, there is no characteristic for the pointing of brickwork. Work with Lego easier, thanks to the grooves masonry turns smooth, does not need large volumes of solution. To hedge, cut out some bricks at the corner slots for fixtures.

Domestic latch brick - a substantially smooth variation corpulent hyperpressed bricks produced by compaction under high pressure without subsequent calcination. Unlike the ceramic, which in particular grades based clay, and the silicate consisting predominantly of sand and lime giperpress produced predominantly from waste mining and processing industry. It can be ground limestone, shell rock, dolomite, marble or crushed stone screening, blast furnace slag. In addition, Stone used bout cutting waste from natural facing stone coal. Minerals cleaned and crushed to a fraction of 3-5 mm and its proportion in the brick is 85-92%. The cement used as binder M 500 (from 8 to 15%), as well as dyes and builders to improve characteristics of the finished product.

If the strength and durability of the ceramic is provided by firing, and silicate - pressure hot treatment steam giperpress then "welded" to firmly homogeneous mass due to extreme pressure - 300 kg / cm².

Such exposure results in adhesion of substances at the molecular level, resulting in a very compact, robust and frost resistant bricks with the correct geometry of the facets.

The use, particularly masonry

Features giperpresovannogo brick make it a versatile, it can be used for masonry bearing and enclosing structures, fences, landscape design objects. However, high density, providing high hardiness and resistance to external influences, in good yields and high thermal conductivity - 1.1 W / (m * S⁰). The homogeneous wall of such bricks cold and needs extra insulation, however giperpress mainly used as a cladding.

Lego, in theory, also suitable for load-bearing walls, since the voids are inserted for reinforcement cords and fill them with the DSP or derivatives thereof, it turns out that something like a monolith with a double-sided brick facing. But since the material is relatively "young", and how he behaves under heavy load in a few decades, knows exactly no, they prefer to clad façades or used for masonry fences, entrances, bowline complexes, summer kitchens or garages.

As the cladding material, it is optimal in view of high decorativeness (precise geometry, large colors) and minimum permeability - the walls are not so polluted because of the rain, it does not form efflorescence. Moreover, if you do not fill the void, facing more and the heat will be better to keep the expense of air gaps around the perimeter. As an option - the voids can be filled insulation, such as perlite or its analogs. The main advantage of the Lego - it is possible to obtain a smooth, beautiful masonry, even if there is no experience mason, that facade is especially important, as services of professionals every year all bite stronger. It has attracted one of the craftsmen of our portal, has chosen for the construction of the castle brick garage in masonry, he used the filling valve and insulation.

desident73 (Member FORUMHOUSE):

Knowledgeable people know how valued a good bricklayer, when laying lego qualification needs no maximum - the hands of the right place for the removal of the first row, next to the machine. Picked up a box of 6 × 3 × 2.4 m in less than a week, a pleasure to work and finish is not necessary for the masonry, it looks natural and presentable. Garage operated winter, warm, is not blown, the period of transition from season to season was also sustained at 100% allocation of any milky liquid was observed. The plans of the construction of the guest house with two floors for the next year.

Shots was his garage, but there are other photos, another craftsman from the forum with the nickname SpbmasterHe used Lego as a liner for your garage.

Pitfalls, or our reality

Of great importance is a manufacturer Lego - proper preparation of raw materials and processing voiced pressure can provide, not all self-made company.

The large plants, with lines for the production of not just giperpressa and its castle species, there is little in our country. The main problem of privateers - to withstand the pressure. Machines, which appeared in a variety of commercially available, most of them are not designed for it. When a lower pressure a less dense, porous structure with a brick, with less strength. The introduction of more binding, to compensate for the lower pressure, partly solves the problem, but also affects the cost. This is not hearsay knows another one of our party has engaged in precisely manufacturing Lego.

Igor_43:

We produce bricks in January 2015 on domestic equipment, a certificate for the products on the strength of the M 150, frostF 50. Theoretically, you can work, but there are some difficulties.

Complexity, according to the craftsman, are divided into three categories.

• Pressure, which gives the machine, not enough - at thirty-five tons obtained porous brick (relative), removable (Initial) strength is small, brick easily damaged during installation on a pallet, hereinafter possible spalling already in the structure, under load. Lack machine pressure to compensate for the increase in% of cement twice.
• Equipment is constantly breaks down, "swim" height adjustment brick. In the production must be "emergency suitcase" - welding machine, a Bulgarian, a tool kit, turning plot, and even better - Machine Building Plant at hand.
• Equipment - not automatic and manual control, therefore, is important the human factor - workers should be responsible, in good faith, with the head and hands, and a team is not easy pick up. The actual performance with the participation of two people total to 600 bricks per eight-hour shift, if three people - up to 1,000, which is considerably less than stated in the machine-tool. The consequence is an increase in the salary fund, raising the cost of rent, heating and other consumables.

But as the production of bricks castle still promising, due to the increasing demand for high-quality material, which can even put a beginner, Igor_43 not retreat, and decided to get rid of all the problems at once, by replacing the press in an automatic, self-developed.

But there is another view - even on media with less pressure to actually get high quality brick. so says shell68Also engaged in the manufacture of Lego.

shell68:

Minimal pressure compensating twice the dose of cement required cement strength gets after steaming and more porous structure is leveled hydrophobizator. With regard to brittleness, when laying on a flat surface are no problems with the formation of cracks and chipped. Also, it was not necessary to increase the pressure, a more thorough preparation of raw materials - division-graded to the large pressing, fine dust fraction, and how to find the optimal ratio.

The photo - a bath wall built of bricks of his castle.

Whether to use Lego as a liner or other purposes - a private matter, but in any case, this is an interesting masonry material, removing the problem of removing the flat walls by non-professionals.

Details about the Lego brick, and its production - in forum thread. As with minimal cost to give a presentable appearance of aerated concrete - article an economical finishing. The material on concrete slab - another popular facade solution. In the video - Master Class on the facing of the facade tiles.
