Compressive Strength Test of Concrete  Detailed
As per IS 456, the individual compressive value of a concrete cube should not be less than 75% from its grade. Example  If the concrete grade is M20, then the individual crushing value should not be less than 15 N/Sqmm. The individual crushing value difference between the cube should not be greater than 15%.

Compression test on concrete  Civil Engineering
The concrete cube test result will be satisfactory but the concrete in the structure would have a much lower strength. 3.8.CONCRETE COMPACTION: Concrete ingredients when mixed have considerable amount of entrapped air depending on the workability. High workable mixes have lesser entrapped air than low workable mixes.

Concrete Compressive Strength Prediction using
Concrete Compressive Strength. The Compressive Strength of Concrete determines the quality of Concrete. This is generally determine d by a standard crushing test on a concrete cylinder. This requires engineers to build small concrete cylinders with different combinations of raw materials and test these cylinders for strength variations with a change in each raw material.
