Viscosity-reducing admixture, ultra-high performance concrete material as well as preparation method and application of viscosity-reducing admixture and ultra-high performance concrete material
The invention provides a viscosity-reducing admixture, an ultra-high performance concrete material and a preparation method and application thereof. Relates to the technical field of cement concrete. The viscosity-reducing admixture provided by the invention is prepared from the following preparation raw materials in parts by mass: 19 to 21 parts of gypsum, 19 to 21 parts of lime, 29 to 31 parts of slag, 14 to 16 parts of calcium carbonate, 4 to 6 parts of glass beads, 3 to 5 parts of nano aluminum oxide, 5 to 7 parts of nano calcium silicate and 5 to 7 parts of an additive, the additives are triethanolamine, sodium hexametaphosphate and potassium silicate. The ultra-high performance concrete material prepared by adopting the viscosity-reducing admixture disclosed by the invention has relatively low mixture viscosity, and meanwhile, the ultra-high performance concrete material prepared by adopting the viscosity-reducing admixture disclosed by the invention has relatively low slump loss.
本发明提供了一种降粘掺合料、超高性能混凝土材料及制备方法和应用。涉及水泥混凝土技术领域。本发明提供的降粘掺合料，按质量份数计，包括以下制备原料：石膏19～21份、石灰19～21份、矿渣29～31份、碳酸钙14～16份、玻璃微珠4～6份、纳米氧化铝3～5份、纳米硅酸钙5～7份和添加剂5～7份；所述添加剂为三乙醇胺、六偏磷酸钠和硅酸钾。采用本发明所述降粘掺合料制备的超高性能混凝土材料具有较低的拌合物粘度，同时本发明制备的超高性能混凝土材料具有较少的坍落度损失。
