摘　　要：传统上可用的坍落度试验是评价新拌混凝土工作性的标准方法。就泵送混凝土而言，工作性主要指可泵性。泵送混凝土由于其自身的特点，单纯以坍落度为指标已不足以评价其可泵性的好坏。因此，迫切需要研究新的工作性评价方法。本文对评价泵送混凝土可泵性的若干方法进行了评述，并初步确定了新拌混凝土的可泵性区间。： Conventional slump experiment is a kind of standard method to appraise workability of fresh concrete．As far as pumpcrete is concernedto a considerable degreeworkability is equal to pumpability．It is unsuitable to appraise pumpability of pumpcrete only based on the slump value target because of the special characteristics of pumpcrete．Thereforenew method to evaluate workability of pumpcrete is expected．In this paperseveral methods to evaluate pumpabliity of pumpcrete are remarkedand pumpability range of fresh concrete is roughly established．
