Testing the Compressive Strength of Concrete — What, why

The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or megapascals (MPa) in SI units. Concrete compressive strength requirements can vary from 2500 psi (17 MPa
