Compressive Strength of Concrete Block: Everything You Should Know

Jun 12, 2022For concrete blocks, the compressive strength is typically around 17.5 N/mm2 or 2500 psi. This means that the blocks can support a load of up to 17.5 N per square millimeter before they start to crack. Compressive strength is tested to determine how much compression a concrete block structure can endure.

Testing the Compressive Strength of Concrete — What, why, & how?

The compressive strength is measured by breaking cylindrical concrete specimens in a compression testing machine. 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.
