Popular building mix M300 – what is it? The planning of the installation of structures that are exposed to operation under increased loads and unfavorable conditions does not imply savings at the expense of the quality of building materials. In most cases, they try to use a cement-sand mixture M300 for mixing mortars.
Its popularity is based on good performance indicators. Which determine the scope of use of raw materials. One of the important indicators is the frost resistance of the M300.
What is frost resistance?
Frost resistance is the ability of a material to withstand a certain number of freeze-thaw cycles without destroying the structure and reducing the safety margin. The base mixture M300 according to GOST is resistant to temperature extremes for 50-100 cycles. The concrete that has gained strength corresponds to the frost resistance class F200 (which means 200 consecutive freeze-thaw processes). But the indicator can be increased with the help of special additives up to 400 cycles.
The degree of frost resistance largely determines the field of application of mortars in which the M300 building mixture is used.
Areas of use of building materials
The basic cement-sand mixture is used for the installation of unheated structures. This can be a garage, basement, utility building. 50 freeze-thaw cycles are enough for trouble-free operation of the frame for 30 years.
The building mixture with additional additives is used for pouring reinforced concrete panels, vertical structures, the frame of hydraulic structures, and foundations for highways. These structures are subjected to high mechanical and physical stress, so they need a large margin of safety. An increase in frost resistance allows maintaining the strength characteristics of concrete based on M300.
