Characteristic Strength Of concrete - Engineering Discoveries
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 ...
