Compressive strength is an essential property in structural materials, for example, mortar, which comprises the interacial transtition zone in concrete, stone, and steel, since material design is normally evaluated in terms of the risk of compression failure. In addition the CBM is known as having strength for compression force. Therefore plenty of standard tests …
