Compressive Strength of Concrete Cubes
Calculation. Compressive Strength of concrete = Maximum compressive load / Cross Sectional Area. Cross sectional Area = 150mm X 150mm = 22500 mm2 or 225 cm2. Assume the compression load is 450 KN, Compressive Strength = (450000 N / 225)/9.81 = 204 kg/cm2. Note – 1 kg is equal to 9.81 N.
