Compressive Strength of Concrete. The compressive strength of concrete is a measure of the concrete’s ability to resist forces trying to compress or push the concrete together. Concrete is very strong in compression, particularly in comparison to the concrete’s strength in tension and flexure which are relatively weak. This is due to the microstructure of the concrete paste
