Viscosity-reducing shrinkage-inhibiting ultra-high performance concrete admixture and preparation method thereof
The invention belongs to the field of building materials, and particularly relates to a viscosity-reducing shrinkage-inhibiting ultra-high performance concrete admixture and a preparation method thereof, the viscosity-reducing shrinkage-inhibiting ultra-high performance concrete admixture comprises the following components by mass: 5-10 parts of nano powder, 20-35 parts of fly ash beads, 15-25 parts of a modified polycarboxylic acid water reducer, 1-3 parts of an air entraining agent and 5-15 parts of super absorbent resin. The concrete admixture prepared by the invention can reduce the viscosity of concrete, improve the early strength of the concrete and inhibit the shrinkage of the concrete.
本发明属建筑材料领域，特别涉及一种降粘抑制收缩的超高性能混凝土外加剂及其制备方法，包括如下质量份组分：纳米粉剂5～10份、粉煤灰微珠20～35份、改性聚羧酸减水剂15～25份、引气剂1～3份和高吸水性树脂5～15份。本发明制得的混凝土外加剂能够降低混凝土粘度，同时提高混凝土早期强度且还能够抑制混凝土收缩。
