摘　　要：传统以坍落度、压力泌水试验为代表的混凝土可泵性评价方法已难以适应现代混凝土。对现阶段国内外几种有代表性的混凝土可泵性评价方法进行了总结与分析,结果表明:混凝土可泵性评价需要多种方法相结合才全面准确,并针对不同特点的混凝土工程,提出了相应的混凝土可泵性组合评价方法。Traditional evaluation methods for concrete pumpability,such as slump and pressure bleeding test,has been difficult to adapt to modern concrete. Several representative evaluation methods of concrete pumpability at home and abroad were summarized and analysed here,and the results showthat in order to evaluate the pump performance of concrete comprehensively and accurately,a variety of evaluation methods must be combined. For different concrete engineering with distrinct characteristics,the corresponding combined evaluation methods of concrete pumpability are put forward in the end.
