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 crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28
