Get PriceEmail contact2021-3-29 Compressive strength test of concrete cube 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.

Get PriceEmail contact2021-2-13 Concrete compressive strength should not be confused with tensile strength. Tensile strength measures the ability of concrete to resist lateral forces, or to resist being pulled apart from either side. While concrete has a fairly high compressive strength, it generally has a poor tensile strength.
