三种聚羧酸系外加剂与水泥及矿物掺合料的相容性对比研究

摘要

Poly carboxylic acid admixtures can obviously improve concrete performance, but their amount and consistency with cement have huge influences on concrete performance. Consistency test is designed and carried out between three poly carboxylic acid admixtures and cement, and it is indicated that powdered coal ash and rock powder mineral admixtures have favorable adjusting function to the consistency between poly carboxylic acid admixture and cement.%聚羧酸系外加剂可较大提高混凝土的工作性能,但其用量及与水泥的相容性对混凝土性能影响巨大.通过设计三种聚羧酸系外加剂与水泥的相容性试验,得出粉煤灰、石粉矿物掺合料对聚羧酸外加剂与水泥的相容性有较好的调节作用.
