【摘要】 为探索煅烧伊利石-绿泥石页岩用作辅助胶凝材料的水化活性，通过X射线衍射（XRD）、傅里叶红外光谱（FTIR）等测试手段分析了在700℃下煅烧不同时间伊利石-绿泥石矿物组成变化，以及对水泥水化产物的影响。结果表明，700℃煅烧后绿泥石结构发生破坏，转变为无定型SiO₂和Al₂O₃，伊利石/云母层状结构塌陷。伊利石-绿泥石页岩煅烧后，硅氧四面体聚合度增加。在水泥碱性环境中，煅烧伊利石-绿泥石页岩中的Si和Al更容易析出，促进了单硫型水化硫铝酸钙（AFm）的形成，改变了水泥水化产物水化硅酸钙（C-S-H）结构，凝胶钙硅比更低，链长更长。煅烧伊利石-绿泥石页岩可用作辅助胶凝材料。更多还原

【Abstract】 In order to explore the hydration activity of calcined illite-chlorite shale as supplementary cementitions materials, the mineral composition change of illite-chlorite shale calcined at 700 ℃ at different time and its influence on cement hydration products were analyzed by means of XRD, FTIR and other testing methods. The results show that after calcination at 700 ℃, the structure of chlorite is destroyed and transformed into amorphous SiO₂ and Al₂O₃, and the illite/mica layered structure collapses and being disordered. The degree of polymerization of silica tetrahedron increases after calcination of illite-chlorite shale. In the alkaline environment of cement, Si and Al in the calcined illite chlorite shale are easier to dissolution, which promotes the formation of AFm, the cement hydration product C-S-H structure is changed, the gel Ca/Si is lower, and the chain length is longer. Illite-chlorite shale calcined can be used as supplementary cementitious materials.更多还原
