Green powder-resistant concrete admixture as well as preparation method and application thereof
The invention provides a green powder-resistant concrete admixture as well as a preparation method and application thereof, and the green powder-resistant concrete admixture comprises the following components in parts by weight: a base material: 40-80 parts of glyceryl phosphate; 240 to 360 parts of 4-hydroxybutyl vinyl polyoxyethylene ether; 3-5 parts of an acrylic emulsion; 4-8 parts of alkali liquor; 2-3 parts of a ferrous sulfate solution; 1-3 parts of ammonium persulfate; 450 to 550 parts of water; a solution A: 30-40 parts of an acrylic emulsion; 20 to 30 parts of water; a solution B: 0.2-0.4 part of vitamin C; 1.1 to 1.6 parts of 3-mercaptopropionic acid; 50 to 70 parts of water; a solution C: 25-45 parts of triethanolamine; 15-35 parts of sodium sulfate; 10 to 30 parts of calcium hydroxide; and 80 to 120 parts of water. The concrete admixture is prepared by adopting a non-toxic and low-toxicity formula, the production process is low in energy consumption at normal temperature, and the concrete admixture has the advantages of small mixing amount, stronger powder resistance and no loss of water-reducing and slump-retaining properties.
本发明提供一种绿色抗粉混凝土外加剂、其制备方法及用途，绿色抗粉混凝土外加剂包括重量配比如下的各组分，底料：磷酸甘油酯40‑80份；4‑羟丁基乙烯基聚氧乙烯醚240‑360份；丙烯酸乳液3‑5份；碱液4‑8份；硫酸亚铁溶液2‑3份；过硫酸铵1‑3份；水450‑550份；A液：丙烯酸乳液30‑40份；水20‑30份；B液：维生素C0.2‑0.4份；3‑巯基丙酸1.1‑1.6份；水50‑70份；C液：三乙醇胺25‑45份；硫酸钠15‑35份；氢氧化钙10‑30份；水80‑120份。该混凝土外加剂采用无毒和低毒的配方调配，生产工艺常温低耗能，并具有掺量小，抗粉性能较强，不损失减水保坍性能。
