低钙高贝利特水泥基材料的水化机理及耐久性研究

The project has studied with the low calcium high belite cement, mainly on its hydration mechanism. It also studied around the workability, mechanical and long-term durability of cement and concrete,after that theoretical analysis will be done for this type of cement hydration and hardening characteristics, which will combine with electrochemical impedance testing and traditional testing methods. And then establish a comprehensive performance evaluation system for low calcium high belite cement, which covers the durability of high belite cement calcium impermeability, frost resistance, thermal performance, anti-carbonation properties, while the correlation study of this type of concrete between pore structure and durability. At last, it will face with the basis of hypocalcemia high durability optimization meathod for belite concrete.
