Lightweight concrete: the benefits, types

Currently, the construction of lightweight concrete density - an extremely important indicator, since for him the lightweight concrete is divided into types:

• structural types (from 1400 to 1800 kg / m3);

• thermal insulation (less than 500 kg / m3);

• structurally-insulating (500 to 1400 kg / m3).

Reduction of this index promotes formation of cells filled with air or use of lightweight aggregates.

advantageous use

It should be noted that the use of materials in this category - quite cost-effective solution. For example, the design of weight loss, as well as increased heat and sound insulation properties of the structure is possible with the participation of the foam.

And then, and another is especially true if we are talking about the construction of a multistory building in the zone of high seismic activity.

Another kind of material - aerated concrete - it allows you to reduce the size of the estimate of construction work at 15-20%.

In this case, labor costs are reduced by almost half. Thus, the overall efficiency is increased by 20%.

All representatives of this class can be divided into three groups:

Porous

They have excellent insulation properties. High pazharobezopasnost. The only "minus" of the material - its complex production process. It is used for floor screeds, monolithic slabs, walls, panels, and so on. D.

large pore

Made on the basis of coarse aggregate (porous) and cement. Most often used in the construction of walls of buildings, whose height does not exceed four storeys. Aggregates: coarse sand, gravel, crushed stone. Representatives of this group are characterized by low thermal conductivity and indicator of efficiency in the manufacturing process.

honeycomb

Mainly found application in low-rise construction.

pros: Easy, quick installation, low cost (compared with a brick), quickly heat their building. Cellular concrete is easy to saw, cut, drilled. He is fire-resistant, resistant to mildew and environmentally friendly. In such a house is easy to breathe. The main feature of the structure responsible for the heat-insulating properties - are uniformly distributed and filled cells with air.

Minus: Low strength, is able to crack, if not reinforced between floors.
