摘要
本文通过对原材料的选择及主要品质指标的研究,采用正交实验对自密实混凝土作配合比设计,并通过极差和回归方程分析水胶比、砂率、粉煤灰掺量、减少剂掺量对混凝土28d抗压强度的影响。结果表明此次配合比能够很好地满足自密实混凝土的强度和工作性能。
It design self-compacting concrete mixture proportion on selecting raw material ,its important property and cross experiment design and research water-binder ratio,sp,ash,superplasticizer for compressive strength of 28 days on range analysis and regression equation. The result shows the concrete mixture proportion can fit strength and work- ability of self-compacting concrete mixture.
