calculate the compressive strength of concrete cubes

calculate the compressive strength of concrete cubes

May 18, 2018 Compressive strength of Concrete Formula: The Compressive strength of specimen can be calculated by dividing maximum load carried by the specimen by cross-sectional area of the specimen cubes. The surface area of specimen: = 150 x 150 = 22500mm = 225cm . Assume, The Max compression load is 450KN. 1KN = 1000N ; 450Kn = 450 100 = 450000N

    How do l calculate compressive strength of a cube in mpa

    Compressive strength of a cured standard mortar cube is calculated by measuring the maximum load applied to the cube to break it (in Newtons) and dividing that value by the cross-sectional area of the cube (in mm^2), calculated from the mean dimensions. The result, reported as N/mm^2 is equivalent to MPa. (ie. 1.0 N/mm^2 = 1.0 MPa)
