The testing method, under method B, is very similar to ASTM C 109. The critical difference is the rate of loading when the cube is compressed. Structural epoxy grouts should be loaded according to the “Load Rate II” spelled out in ASTM C 579. When tested under Load Rate II, the rate of load applied to the cube is controlled by movement over

For normal concrete and HSC, the concrete compressive strength test results from cube specimens are generally higher than cylinders specimens [6]. As states in BS 1881, the compressive strength of concrete gained by cylinder specimens is equal to 0.8 times of the compressive strength gained by cube specimens.

Compressive strength of concrete cube test is the most important strength test for concrete. This single test gives an idea about all the characteristics of concrete. Concrete are very strong in compression. It is assumed that whole of the compression will be taken up by the concrete at the time designing any RCC structure.
