The Concrete strength is calculated by dividg the maximum load at failure by the average cross sectional area. Concrete compressive strength requirements can vary from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa) and higher commercial structures. Higher strengths up to and exceedg 10,000 psi (70 MPa) are specified for certa applications. ## How to calculate compressive strength of concrete cube dencity

Then the readg on the mache is divided by the area of cube to get the actual compressive strength. For example area of the cube is 150mm X 150mm = 22500mm2 and the readg from the mache is 751000 n/mm. Then the compressive strength of the cube will be 751000/22500 = 33.37 N/mm. ## Computg the Compressive Strength of Concrete ... - IASJ
