基于正交试验的钢纤维自密实混凝土配合比设计分析

Design and analysis of mix proportion of steel fiber self compacting concrete based on orthogonal test

自密实轻骨料混凝土由原来的单一物质变为当前使用较多的添加钢纤维自密实轻骨料混凝土,其抗裂性能以及抗水渗性能得到提升。本文针对国内外钢纤维自密实混凝土进行分析,使用绝对体积法,确定钢纤维自密实混凝土的最终配合比。

The self compacting lightweight aggregate concrete in China has changed from the original single material to the self compacting lightweight aggregate concrete with steel fiber.Compared with traditional concrete,this method can increase its crack resistance and water permeability resistance.In this paper,the steel fiber self compacting concrete at home and abroad is analyzed,and the absolute volume method is used to finally determine the final mix proportion of steel fiber self compacting concrete.
