Compressive Strength Test Of Concrete

Compressive Strength Test Of Concrete

The compressive strength of concrete. otherwise, the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete. purpose of this test. assume a slab at our site is designed to cast m25 grade of concrete, but we could not define its strength in the semi-solid.The compressive strength of parent rock does not exactly indicate the strength of aggregates in concrete. for this reason assessment of strength of the aggregates are made by using a sample bulk aggregates in standardized manner. the test conducted to know the compressive strength of aggregate is known as aggregates crushing value.
