水化硅酸钙晶种研究进展

Research progress of C-S-H crystal seeds

水化硅酸钙(C-S-H)是人们使用最多的材料水泥的主要成分,其对水泥基材料的强度有很大贡献。人工合成CS-H晶种作为纳米材料掺入水泥基材料后,可以改变水泥基材料的水化产物进程,甚至可以为水泥基材料赋予特殊的性质。为此,介绍C-S-H晶种的吸附作用和对水泥的外加剂作用,以及目前关于C-S-H晶种改性方面的研究。

Calcium silicate hydrate(C-S-H)is the main component of cement,which is the most commonly used material by humans,and it makes a significant contribution to the strength of cement-based materials.The artificially synthesized C-S-H crystal seeds can be incorporated into cement-based materials as nanomaterials,which can alter the hydration process of cementbased materials and even endow them with special properties.In this paper,the adsorption of C-S-H seed crystal and the admixture for cement hydration are reported,as well as the current research on the modification of C-S-H seed crystal.
