If it comes to the construction of foundations, paths around the house in a personal plot or in the country, then many immediately recall that it is necessary to purchase crushed stone. Without crushed stone, the implementation of these work becomes almost unrealistic, since it is one of the components of manufacturing technologies.
Each type of work requires the use of one or another variety of this material. You can buy crushed stone, which will be ideal for certain work if you take into account all its properties. When making a purchase, it is necessary to take into account the following:
Flying. This concept denotes the presence in the crushed stone scattering of the zooren with needle acute shape. The word “breaming” itself comes from the word bream and implies a flat form of bream. Stones of this form are not recommended to be added in the manufacture of foundations, since they increase the likelihood of shells and gaps. For concrete suitable there will be a crushed stone that has a cuboid shape.
Frost resistance. This parameter indicates the number of circles of freezing and defrosting, which can withstand crushed stone without destruction. Particular attention is paid to this parameter in those regions where significant temperature changes are observed, it affects the strength of the construction.
Hardness. This indicator determines the ability of crushed stone to withstand the load without destruction. This indicator in crushed stone mass is largely determined by its composition. So the highest loads can withstand the gravel, which contains granite and marble. These stones separately have a high level of hardness and are almost not destroyed under the mechanical effect.
Radioactivity. This is another important indicator that can significantly affect the decision on the use of crushed stone in one case or another. All stones contain radioactive elements. If they are contained in large quantities, then such a gravel cannot be used in the construction of residential buildings. Especially radioactive crushed stone is used only in the construction of road surface and similar buildings.
