摘　　要：在对内蒙古高铝粉煤灰以及硅钙渣和脱硫石膏成分分析的基础上,进行了以硅钙渣、脱硫石膏以及高铝粉煤灰为主要原料制备硅钙板的试验研究。结果表明,在硅钙渣50%、水泥10%、粉煤灰20%、脱硫石膏20%的最佳配比条件下,可制得符合JC/T564.2—2008《纤维增强硅酸钙板第2部分:温石棉硅酸钙板》中D1.5类Ⅱ级要求的硅钙板,达到A级不燃标准,抗折强度达到9MPa以上。On the basis of analysis to chemical composition of the calcium silicate slag, desulfurization gypsum and the high- alumina fly ash,preparation of calcium silicate board with calcium silieate,desulfurization gypsum and the fly ash as the main raw material is studied. The properties of the products achieved the requirements of Ⅱ-level in D1.5 category in national prescriptive JCFF 564.2--2008Fiber reinforced calcium silicate boards,part 2：asbestos calcium silicate boards. It reaches Class A noncom bustible standards,flexural strength reaches more than 9 MPa. And the best ratio of components was follows：50% of calcium sili- cate slag, 10% of cement, 20% of fly ash,and 20% of desulfurization gypsum.
