Concrete Compressive Strength- Cube Test and its Procedure

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.
