Since concrete for the strip foundation should be strong, its selection is made according to the brand, which determines this indicator. It indicates the maximum bearing capacity of 1 kV. cm. Square. Since the load is measured in kilograms, then it becomes clear that the M200 withstands 200 kg load for 1 cm2. If they know the bearing capacity of the structure, then the brand of concrete is very easily calculated for her.
