How to Determine the Compressive Strength of Cement

Jun 08, 2012 · Then divide each crushing load value by the area of cross section of cube which in this case is 4 in 2. This will give the compressive strength of each cube which may vary in value. Then take the average of these values by summing them dividing them by number of cubes. This will be the compressive strength of that mortar. ASTM Standards Weight of Water
