摘要
高性能混凝土在新拌状态下不仅流动性大，且具有较高的塑性粘度，因此用传统的坍落度方法难以全面地反映其工作性。作者设计了一种较为科学并有效地评价高性能混凝土工作性的方法，采用Ｌ型流动仪，以大量不同配比的高性能混凝土为对象进行了试验研究，检验了该方法的有效性、科学性与重复性。
Fresh high performance concrete has not only large fluidity,but also has a certain plastic viscosity.Hence,it is difficult to evaluate its workability totally by traditional slump value method.In this paper,a more efficient and reasonable method to evaluate the workability of high performance concrete is proposed.Then, a large number of fresh high performance concrete tests with different proportions are performed.Effectiveness,reasonability and repeatability of the proposed method are studied by measuring the behavior using L type flow meter.
