Concrete is a mixture of cement and aggregate. When a certain amount of water is added When the cement hydrates to form a microscopic opaque lattice structure to wrap and combine the aggregate to form an overall structure, usually the concrete structure has a strong compressive strength, but the tensile strength of the concrete is low, usually only one tenth of the compressive strength For a period of time, any significant tensile bending action will cause the microscopic lattice structure to crack and separate, resulting in structural damage, and most structural members have the demand for tensile stress inside, so unreinforced concrete is rarely used. Used alone for engineering.

Usually, people add reinforcing materials such as steel bars to concrete to work with it. The steel bars bear the tensile force, and the concrete bears the compressive stress. Due to the important role of reinforced concrete, it is necessary to test its mechanical properties during use.
