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。本研究以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 effect of Mortar＇s rheologic system and the shape quality and grading of coarse aggregates.When mortar had well behavior,the important attribute influence self-compacting concrete＇s working performance are coarse aggregates＇ shape and gradation.The method this paper have been used to investigate the ＇ self-compacting＇ theory is to investigate the influence of coarse aggregates＇ shape index and gradation in self-compacting concrete＇s rheological behavior and working performance under fixed high performance mortar.
