Due to non-uniformity in the materials and less voids detection at rebound hammer, the crushing cube test showed 16.6% more compressive strength than the hammer test in varied curing and 20% in MBC. As the hammer test is a non-destructive testing, the compressive strength is at reserve side compared to crushing strength.The compressive Strength of the concrete cube test provides information on all concrete properties. This single test determines whether or not the concreting was done correctly. Concrete compressive Concrete Compressive Strength -Cube Test [PDF],

1. In general, a lot of literature is available on compressive strength of cube or cylinder specimens. However, in practice, reinforced concrete is used in the field, especially for large structures.For example, a normal concrete cured entirely in. air, will have a strength at 28 days about half that of the same mix cured in water. Similarly, a specimen cured in water at 130C will have a strength at 7 days about 70%. of that of the same mix cured in water at 460C. Because of these variations, it is.Crushing Strength of Concrete PDF Calibration Concrete
