COMPRESSIVE STRENGTH • Compressive strength is the capacity of a material or structure to withstand axially directed pushing forces. • When the limit of compressive strength is reached, brittle materials are crushed.

Characteristic Strength Of Concrete Engineering Discoveries

Author. Engineering Discoveries. The classification of concrete grades is based on their compressive strength. Each concrete grade e.g. C30 37 is characterized by two equivalent strengths, which in this specific example are 30 MPa and 37 MPa. The first is the characteristic strength f ck of a standard concrete cylinder and the latter is the.
