[0002] Concrete, simply referred to as "tóng (砼)": It refers to the general term of engineering composite materials in which the aggregate is cemented into a whole by cementitious materials. Usually, the term concrete refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as the aggregate; and is mixed with water (which may contain additives and admixtures) in a certain proportion and stirred. It is widely used in civil engineering.

[0003] Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its scope of use very wide.
