How To Calculate Compressive Strength Of Concrete Value? – Formula. Compressive Strength of concrete cube = Maximum load/Area of the cube. Example Calculation. Assume that the compression load is 375 KN (1 Kg = 9.81 N) Cross Sectional Area – 15 x 15 = 225 Sqcm. Compressive Strength = (375 x 1000/225) = 1666/9.81 = 169.82 Kg/Sqcm. Lab Report

The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of service loads.
