A garage for a car owner is a necessary structure. It is built from different materials: metal, brick, blocks, wood. In this article we will deal with the blocks for the construction of the garage. What they are, what components they are made of, and also denote their technical characteristics.
Actually, the types of piece block materials on the market not so little. They differ from each other in the number and variety of components, and more precisely, the difference in one is the composition.
According to this principle, wall blocks are divided into the following types:
cinder blocks ;
of cellular concrete : foam and gas blocks;
gas silicate .
Consider each species separately, we denote their characteristics.
It is necessary to begin with the fact that this kind of wall material is a pure concrete product. There is nothing more than cement, sand, crushed stone (gravel) and water in it. Hence the high strength of the product.
Concrete becomes durable as a stone when dry, so structures made of concrete are often called artificial stone. But it should be noted that the concrete used in the production of blocks may be different. Hence the different characteristics of this material.
For example, blocks of heavy concrete, the density of which varies in the range of 1800-2500 kg / m³. It turns out that this is only because the composition of the recipe uses a large stone of heavy and durable rocks: basalt, granite, diabase, limestone and so on. Note that heavy concrete blocks are expensive, and more often they are used for the construction of foundations.
Light concrete blocks with a density of up to 2000 kg / m³. They are used for the construction of walls. The composition of this material includes as a filler light granular products, as well as bulk materials, for example, perlite or agloporite.
The third type in this category are blocks of cement-sand mixture, reinforced with steel mesh or wire mesh with a diameter of 6 mm. Manufacturers offer two versions of this material: hollow and corpulent. It should be noted that blocks of this type have the same strength as products made from heavy concrete, but they are several times cheaper. Therefore, when the question is raised, of which blocks it is better to build a garage, then in this category it is better to give preference to cement-sand.
A huge brick deficit preceded the appearance of cinder blocks. It was not enough all the time, especially in private housing. Therefore, it was decided to start mass production of this wall building material with the addition to the cement mortar of the so-called waste filler, which was supplied almost free of charge. These were slags from blast furnaces and thermal power plants that operated on coal. Slag is useless material and is difficult to dispose of. The appearance of the production technology of slag stones solved two serious problems at once.
It should be noted that today, under the concept of cinder blocks, they produce and sell piece wall material with different fillers. That is, slag will not necessarily be used in it. Instead, sawdust, shell rock and other cheap ingredients are added to the solution, which primarily reduces the weight of the finished product. But at the same time, the strength of the material is not lower than blocks of lightweight concrete.

The popularity of cinder blocks is huge. They are still used in low-rise construction, as the main building material for the construction of walls. Depending on the type of filler used, cinder blocks have different characteristics:
density from 750 to 1500 kg / m³;
thermal conductivity 0,027 to 0.65 W / m K, compared to a brick - 0.8 W / m K;
compressive strength corresponds to the materials of the brand from M35 to M150;
the service life is up to 100 years, if we take into account the negative impact of natural loads, if the house roof is durable and reliable the house from slag stones will serve not less, than brick.
It should be added that this wall material has its disadvantages:
unpresentable appearance ;
moisture resistance is not the highest;
the difficulty of fastening interior objects to walls built of cinder blocks.
But this material keeps its popularity firmly.The reason - the low price, plus ease of installation. We also add that today manufacturers offer cinder blocks with one decorative side. The original approach to solving the problem of decorating buildings.

Wall insulation has always been given special attention. And although for many garages this is not fundamentally important, blocks with the addition of expanded clay are no less popular today than with filler in the form of slags. Their main distinctive feature is low thermal conductivity within 0.14-0.65 W / m K. The difference in performance is quite large, it depends on the amount of cement applied to the solution. The larger it is, the higher the thermal conductivity of the material.
Today, manufacturers offer two types of blocks made of expanded clay concrete:
structural , of which walls are constructed;
heat-insulating , which are used to insulate buildings.
We are interested in the first option. Here are its specifications:
specific gravity from 600 to 1800 kg / m³;
strength 35 to 500 kg / cm²;
frost resistance - up to 500 cycles;
water absorption - up to 10%;
temperature limit from -180С to + 1050С;
sound insulation within 50 dB;
vapor insulation within 0.4.
Blocks for a keramsit concrete garage are now increasingly being used in the construction of garages. Many car owners began to realize that a dry and warm garage is a long-term operation of the car without the formation of corrosive areas on the body.

This building material got its name only because its structure is a solution filled with voids (cells). Today this type of piece wall article on the roar is represented by two positions: foam and gas-concrete blocks. Accordingly, they are made of foam concrete and aerated concrete. Consider their differences from each other.
So, foam concrete is a standard concrete solution to which special substances are added (organic or synthetic). They are called foaming agents. That is, when in contact with water, substances begin to form foam. Inside the solution, small bubbles with air are formed due to the foam. The solution is poured into molds, where it turns into stone. And the air remains so inside, making the structure of the material porous.
The video shows the production of foam concrete:
Aerated concrete is produced using a completely different technology. Firstly, lime and aluminum powder are added to the concrete mortar. Interacting with each other with the participation of water, both substances enter into a chemical reaction in which hydrogen is released. So it forms bubbles inside the mixture. But a chemical reaction can occur only under pressure and with increasing temperature, therefore, aerated concrete blocks are produced in special equipment, which is called an autoclave. Inside, a high pressure is created, and the temperature rises due to the formation of saturated steam.
Also note that foam blocks are material formed in special shapes with the exact dimensions of the final product. Aerated concrete products - a material with large dimensions, which is then cut under the required (standard) parameters. For this string is used. It turns out that foam concrete has a structure with closed pores, gas concrete with open pores. Therefore, the second water absorption is much greater than the first. Hence the important requirement for garages erected from gas blocks. The walls of the building must be protected, it can be plaster or any other type of cladding.
