Concrete composite water reducing agent and preparation method thereof
The invention relates to the field of concrete admixtures, and particularly discloses a concrete composite water reducing agent and a preparation method thereof.The concrete composite water reducing agent comprises cationic modified polycarboxylic acid, triethanolamine and superfine slag powder; the cationic modified polycarboxylic acid comprises isopentenol polyoxyethylene ether, hexadecyl trimethyl ammonium bromide, an oxidizing agent, a component A drop and a component B drop, and the component A drop comprises an acrylic monomer and an unsaturated acid ester monomer. The preparation method comprises the following steps: S1, preparing cation modified polycarboxylic acid; and S2, mixing the superfine slag powder, triethanolamine and cationic modified polycarboxylic acid, uniformly stirring, drying at room temperature for 1-2 hours, and drying in an oven at 40-50 DEG C for 1.5-2.5 hours to obtain the concrete composite water reducing agent. The concrete composite water reducing agent prepared by the invention is suitable for cement with high C3A content.
本申请涉及混凝土外加剂领域，具体公开了一种混凝土复合减水剂及其制备方法，混凝土复合减水剂包括阳离子改性聚羧酸、三乙醇胺、超细矿渣粉；所述阳离子改性聚羧酸包括异戊烯醇聚氧乙烯醚、十六烷基三甲基溴化铵、氧化剂、A组分滴剂和B组分滴剂，所述A组分滴剂包括丙烯酸单体和不饱和酸酯单体。其制备方法为：S1、制备阳离子改性聚羧酸；S2、超细矿渣粉、三乙醇胺与阳离子改性聚羧酸混合，搅拌均匀后室温干燥1‑2h，烘箱40‑50℃干燥1.5‑2.5h，得到混凝土复合减水剂。本申请制备的混凝土复合减水剂适用于C3A含量高的水泥。
