本文采用降粘型聚羧酸系减水剂,并通过对混凝土配合比的合理优化设计配制出C60高抛自密实混凝土,以解决其存在的高填充性与高黏性,高流动性与抗离析性之间的矛盾。实践证明,优化后的配合比所制备的混凝土现场和易性良好,能达到自密实混凝土填充效果,抗离析性好,结构实体表观质量好。
In this paper, the viscosity reducing polycarboxylate superplasticizer, and through the rational design of the concrete mix rationally formulated C60 high throwing self-compacting concrete to solve its existing high filling and high viscosity, high liquidity and resistance Discrepancy between the contradictions. Practice has proved that the optimized mixture prepared by the site of good workability and easy to achieve self-compacting concrete filling effect, anti-segregation is good, the apparent quality of the structural entities.
