摘　　要：通过对掺入一定量硫酸铝的硫铝酸盐水泥的抗压强度和抗渗性能的测定,借助XRD、压汞仪等测试手段,研究和分析了硫酸铝对硫铝酸盐水泥水化的影响及其防渗机理。结果表明,掺入适量的硫酸铝,能改变硫铝酸盐水泥熟料的水化进程,从而改善硫铝酸盐水泥基防渗堵漏材料的早期强度和抗渗性能。The compressive strength and impermeability of sulphoaluminate cement mixed with aluminum sulfate are tested. The influence of aluminum sulfate and the percolating - proof mechanism are studied and analyzed by means of XRD and press mercury tests. It is concluded that the hydration of sulphoaluminate cement changed with the addition of aluminum sulfate. The early compressive strength and impermeability are improved.
