Characteristic Strength Of concrete - Engineering .

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 characteristic strength of a standard concrete cube.

Effect of Aggregates on the Properties of Concrete | .

The crushing strength test discussed above has been found insensitive to the variation in strength of weaker aggregates. Therefore when such aggregates are tested by this method, they do not give true picture, because they get crushed before the full load of 40 tonne has been applied and get compacted causing the plunger to jam.
