摘要
自密实混凝土的自密实性能的优劣,可以以砂浆基材的流变体系和粗骨料品质、级配的综合作用来评价。在砂浆基材性能良好的情况下,粗骨料的粒形和级配等成为了影响自密实混凝土工作性能的重要因素。本文以使用性能良好的砂浆基材为前提,研究了粗骨料的形状指数和级配对自密实混凝土拌合物流变性能和工作性能的影响。
The self-compacting performance of the concrete mixture could be evaluated with the combined effects of mortar＇s rheological system, the shape quality and grading of coarse aggregates. With the ideal performance mortar as a precondition, the important attributes influencing self-compacting concrete＇s working performances are coarse aggregates＇ shape and gradation. Provided that the mortar＇s performances are ideal, this paper, having adopted the method to investigate the self-compacting theory, is to study the influence of coarse aggregates＇ shape indexes and gradations in self-compacting concrete＇s rheologieal behaviors and working performances.
