摘　　要：以高铝矾土熟料为主要试验原料,研究了硅微粉和-Al2O3微粉对低水泥浇注料体积密度、显气孔率、抗折强度和耐压强度等性能的影响,并确定了两种微粉在低水泥浇注料中的最佳掺量。Low cement caastables were prepared with high alumina bauxite chamotte as main starting materials. Influence of micropower addition on properties of low cement castables was studied, such as volume density, apparent porosity, curshing strength, folding strength and so on. And then the best quantity of the two kinds of micropower in low cement castable was confirmed.
