Date: 1/1/1991. Abstract: The web crushing strengths of 16 reinforced and prestressed concrete I-beams are reported. The principle variables of the test specimens are the ratio of yield force in the prestressed steel and the area of vertical stirrups. The test strengths are compared with the upper limit on shear strength given by the ACI

Concrete mixes are classified by their grade having specified crushing strength at 28 days as measured in standard conditions with 150 mm × 150 mm × 150 mm size cube, which means the grade of concrete corresponds to its characteristic compressive strength . M-20 shows the crushing strength of that cube having size 150 mm at 28 days is 20 N/mm2.

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

The characteristic strength of concrete is the result of the compressive strength of the concrete cube test. The design strength is the required strength of concrete to be designed as per the IS code. For example, assume that the strength of concrete required M25, and the target design strength is 28.5 N/Sqmm.
