Explanation

It is also called compressive strength. An important mechanical property index of materials used for bearing compression load, which represents the ability of materials to resist compression load without failure. It is calculated by the ratio of the maximum load before fracture of the shrink sample to the original cross-sectional area of the sample. For brittle and low plastic materials (such as cast iron, cement, ceramics, etc.), the rejection strength has a clear value when the fracture occurs under compressive stress. Because the longitudinal and transverse structures are obviously different, the compressive strength values in the parallel and vertical directions are quite different
