2021/01/14The strength measure with concrete cube or cylinders by civil engineers at the construction site. Cube or cylinders make during casting of the structural member and after hardening, its cure for 28 days. Then the compressive strength test conducted to find the strength. Regular grades of concrete are M15, M20, M25, etc.

2017/05/13What is the difference between Concrete Cube and Cylinder Strength test? The Compressive strength test will result in a compressive load on the cube and the cylinder during the test procedure. This process will result in the Lateral Expansion of the sample which will result in the Poisson's ratio effect. The figure-1 below shows the
