The construction of houses and roadway is not rarely carried out using a concrete mixture. From concrete make bases and paving slabs. The components of concrete, in most cases, are sand, gravel or gravel, water and several other components that are not the main ingredients. In general, it is believed that the mason Joseph Apsin invented the concrete mixture somewhere in 1824, although this fact is unreliable. Apsin came up with only the binding component – cement, which is part of concrete, and in many respects improved concrete. The mason interfered with the limestone with clay, heating them. Having received a homogeneous mass, the Englishman carefully rubbed it to the powder and added water. This procedure added strength to the material.

At first glance, concrete has been made for centuries. However, it is easily broken. Concrete material is greatly predisposed to the formation of cracks. The best experts, including a highly qualified builder-builder, master or mason, are not able to finally prevent the appearance of cracks in concrete. You can only reduce cracks. So still why the concrete material cracks? Когда все составляющие смешиваются с водой, то получается вязкая масса, после отвердения которая образует бетон. The mass freezes due to the evaporation of water. The place of water is occupied by the filler and astringent. It is such a process that leads to the appearance of cracks. Cracks appear as a result of cooling or warming. For example, during the rain, the concrete mixture absorbs a certain amount of moisture. After the rain, with the onset of heat, the water that has leaked into concrete is heated. By inertia, concrete expansion occurs. Particles of concrete mixture are removed from each other, and cracks arise. The occurrence of cracks in the concrete mixture is almost impossible to avoid, but you can maximize their negative effect.
