As you know, concrete has various brands — the higher it is, the better the quality of the composition. Actually, the concrete brand is a value denoting its strength when solidified in ideal conditions, that is, at a temperature of at least 15 ° C for 28 days. The composition of any concrete mixture necessarily includes water, which at a temperature below 0 ° C turns into ice, thereby increasing in volume. This leads to the fact that concrete begins to expand and deform, making the structure of the unreliable.
