بيت /Methof Of Testing Of Compressive Cube Strength
Construction practice cube test is one of the vital test which is performed to determine the strength of concrete which has been already used in the construction. Cube testing is a destructive testing method of concrete testing, as cubes are crushed in compression testing machine. The mostly tested cubes in practice are of 150x150x150 size in mm.
