粘塑剂对免振捣自密实混凝土性能的影响

The influences of plastic-viscous admixture on the performances of self-compacting concrete

通过复合使用高效减水剂和适量粘塑剂,可很好地解决免振捣自密实混凝土大流动性与高抗分离稳定性之间的矛盾。本文作者详细地研究了粘塑剂对自密实混凝土工作性、凝结时间、力学性能及体积稳定性的影响。所得结果对自密实混凝土中正确有效地使用粘塑剂具有指导作用。

The conflict of high fluidity and high antiseparate stability was perfectly solved through using superplasticizer and suitable plasticvicous admixture in selfcompacting concrete.In this paper,the influences of plasticviscous admixture on workability,set time,strength performance and volume stability of selfcompacting concrete was detailedly studied.The results can accurately direct the use of plasticviscous admixture in selfcompacting concrete.
