The most common test for hardened concrete is the compressive strength, at a It helps in determining the rate of gain of strength of concrete samples if cubes
The cubes are smaller compared with the cylinder specimen of concrete, and the The height/diameter ratio equal to 2, the compressive strength of cylinder
height-to-diameter ratio of a specimen is less than 2.0. However, the ed concrete, 100mm cubes (l/d = 1.0) produce a comparable compressive strength.
