In concrete, cement, as a cementitious material, reacts chemically with water to form a hardened body, which firmly bonds the sand, gravel and other aggregates scattered in it, thereby giving concrete physical and mechanical properties such as compression resistance, tension resistance and durability. Concrete not only has good plasticity and can be made into components of various shapes and sizes as needed, but also has high strength and wear resistance after hardening, and can resist wind and rain erosion, chemical erosion and microbial erosion. Therefore, it is widely used in various projects such as building structures, roads, bridges, tunnels, etc. In addition, by adding different admixtures and admixtures, the performance of concrete can be further improved to meet various special engineering needs.
