摘　　要：研究了铝酸盐水泥、硬石膏掺量对自流平砂浆抗压强度的影响。试验结果表明:单掺硬石膏和铝酸盐水泥,各龄期砂浆的抗压强度均降低,且掺入铝酸盐水泥时,砂浆的抗压强度降低比较显著;并通过正交试验,研究了二者对砂浆抗压强度的影响,通过层次分析法得出各因素各水平的影响权重和优选方案。The influence of different dosages of sulphur aluminate cement and anhydrite on self-leveling mortar compressive strength were studied.Experimental results showed that： when mixed with either anhydrite or sulphur aluminate cement, the compressive strength of mortar were all decreased,especially when mixed with sulphur aluminate cement,it decreased more significantly;Through orthogonal tests, we analysed both influences on mortar compressive strength, and achieve impaction factors and optimal schemes of various elements on different levels through analytic hierarchy processes.
