Multi-element composite bare concrete admixture and preparation method thereof
The invention discloses a multi-element composite bare concrete admixture, which is characterized by comprising the following components in percentage by mass: 11.0 to 25.0 percent of polycarboxylate superplasticizer, 0.5 to 3.0 percent of viscosity modifier, 0.01 to 0.1 percent of air entraining agent, 0.01 to 1 percent of defoaming agent, 0.1 to 8.5 percent of retarder, 2.0 to 9.0 percent of styrene polymer emulsion and 53.4 to 86.4 percent of water. The admixture enables the concrete to have higher toughness, crack resistance and impermeability, lower bleeding rate and water content, better fluidity and plasticity retaining property, simple preparation process, no need of heating, energy conservation and environmental protection, and is suitable for popularization and application.
本发明公开了一种多元复合清水混凝土外加剂，其特征在于，各组分按质量百分比为：聚羧酸减水剂11.0％‑25.0％、黏度调节剂0.5％‑3.0％、引气剂0.01％‑0.1％、消泡剂0.01％‑1％、缓凝剂0.1％‑8.5％、苯乙烯聚合物乳液2.0％‑9.0％、水53.4％‑86.4％，该外加剂使混凝土具有更高的韧性、抗裂性和抗渗性，具有较低的泌水率比和含水量，而且有较好的流动性和保塑性，制备工艺简单，无需加热，节能环保，适合推广应用。
