Answer / rashid imam

Compressive strength of concrete can be obtained by a laboratory test called as compressive strength test . It involves a compression testing machine or CTM , a 150 mm cube of concrete ( after 28 days of maturity ) whose strength is to be tested . Now the process involves that the cube is placed in the machine and load is gradually applied and the deformation is noted . The load at which the cubes breaks down is called it's compressive limit.

If at site iam supposed to get M30.But by mistake i got M20 mix. How could I differentiate the mix before placing?
