# Calculate The Compressive Strength Of Concrete Cubes

• ### What is the Characteristic Strength of Concrete?

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. Compressive strength of concrete at days . The concrete takes 24 hours to attain 16% of its strength, and the strength
