介绍了国内标准与ASTM标准测试水泥基灌浆材料流动性能所采用的两种方法：截锥圆模法和流锥法，试验比较了水泥基灌浆材料在两种测试方法下的性能表现差异，结果表明国内标准仅采用截锥圆模法无法全面表征大流动度水泥基灌浆材料的流动特性。采用自制防沉剂，配制了同时满足GB/T 50448-2008和ASTM C939-2012要求的具有高流动性能的水泥基灌浆材料。

Two test methods were introduced for the flow property testing of cement based grouting material ,truncated cone method and flow cone method.Experiments were carried out to compare the flow performances of same cement based grouting material by the two dif-ferent test methods,and the result showed that the flow property of cement based grouting material with high fluidity could not be fully characterized only by the truncated method.Cement based material with excellent flow performance was prepared by using the self-made anti-settling agent,and it could meet the requirements of both GB/T 50448-2008 and ASTM-C939-2012.
