As the main cementitious material of concrete, the quality of cement largely determines the quality of concrete, especially in pavement concrete, which not only requires compressive and flexural strength that meets the specifications, but also has relatively high requirements for fatigue resistance, impact resistance, and abrasion resistance after cement hardening.
In cement clinker, it is beneficial to increase the C4AF and C2S content appropriately to improve the fatigue resistance, impact resistance, and wear resistance of concrete while ensuring sufficient C3S content to meet strength requirements and a flux mineral content of 19% to 20%.
