    Test Procedure of Compressive Strength of Concrete Cubes: There are two types of specimens either cubes of 10 cm*10 cm*10 cm or 15 cm*15 cm*15 cm both depend on the sizes of aggregates used. Commonly size of 15 cm*15cm*15 cm cubical molds are used for most of the works. Concrete is poured and suitably forced so that there will be no voids.

    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 test.
