concrete structure, the compressive strength of concrete is an essential element. 28days compressive strength of concrete is usually considered as the design strength.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 ...
