依据负温混凝土的可泵性条件，研究了在最优可行性允许的泌水量为７０ｍｌ－９０ｍｌ（４２２／～５４３／）范围内，可泵高度为大于１００ｍ时的负温泵送混凝土中的细粉料含量，并由此评价了负温混凝土拌合物可泵性的指标 According to the pumpability conditions of negative temperature concrete, the negative temperature pump with a pumpable height of more than 100m was studied in the range of 70ml-90ml (422/-543/) of bleeding volume with optimal feasibility. Sending fine powder content in concrete, and thus evaluating the index of pumpability of negative temperature concrete mix
