摘　　要：本研究设计了一种流动性测试方法,既可测试新拌磷酸镁水泥浆体的变形速度,又可测试其最终变形能力。对新拌磷酸镁水泥浆体的流动特性有较高的敏感性。通过自制流动测试装置,可测试出在不同搅拌工艺和配比参数下配制的新拌磷酸镁水泥浆体的变形速度和最终变形能力,了解其流动特性变化规律。A new testing method which could test both deformation velocity and the end-deformability of magnesia-phosphate cement paste was designed in this study; it possesses relatively high sensitiveness to freshly mixed magnesia-phosphate cement paste. The deformation velocity and the end-deformability of the freshly mixed magnesia-phosphate cement paste which was prepared by different stirring process and mix proportion parameters can be tested and the variation of its fluidity can be understood.
