Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as watercement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.

Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete''s ability to resist loads which tend to compress it. The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine. The compressive strength of concrete is calculated by the failure load

Highstrength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normalstrength concrete, highstrength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
