摘　　要：本文用水玻璃激发赤泥和矿渣而得到了高强的无机胶凝材料———碱赤泥矿渣胶凝材料。研究了赤泥掺量、水玻璃品种和掺量以及磷酸钠的掺量对这种胶凝材料强度的影响。通过正交试验确定了其最佳的质量配比。A new kind of cementitious material with high properties,alkali\|activated red bauxite mud and slag cementitious material (AARMS),is developed,in which the blend of red bauxite mud and slag is activated with water glass.The influences of different factors including red bauxite,water glass and Na\-3PO\-4 on the hydration of this cementitious material is detailly studied.An optimum formula of AARMS is obtained through orthogonal experiments.Its hydrated products are identified and variation of these hydrated products are studied with XRD. \[
