Concrete early-strength high-efficiency water reducing agent and preparation method thereof
The invention relates to a concrete early-strength high-efficiency water reducing agent and a preparation method thereof. The concrete early-strength high-efficiency water reducing agent is prepared from a polyether macromonomer, acrylic acid, acrylamide, sodium methallyl sulfonate, a chain transfer agent, a redox agent, 2-hydroxyethyl-2-hydroxypropyl methyl ether cellulose, fly ash-carbide slag composite powder and deionized water. Wherein the polyether macromonomer is composed of a compound of allyl polyglycol ether and alkylphenol polyglycol ether. According to the scheme provided by the invention, the slump loss problem of the current polycarboxylate superplasticizer can be improved and relieved under the condition that the doping amount is relatively low, and the failure of adsorption and dispersion effects is improved; meanwhile, the strength of the concrete can be improved.
本申请涉及一种混凝土早强高效减水剂及其制备方法。该混凝土早强高效减水剂，由聚醚大单体、丙烯酸、丙烯酰胺、甲基丙烯磺酸钠、链转移剂、氧化还原剂、2‑羟乙基‑2‑羟丙基甲醚纤维素、粉煤灰‑电石渣复合粉体和去离子水制成；其中，所述聚醚大单体由烯丙基聚乙二醇醚和烷基酚聚乙二醇醚的复合物组成。本申请提供的方案，能够在掺量较低的情况下提升缓解当前聚羧酸减水剂的坍落度损失问题，提高吸附分散作用的失效；同时还能够提升混凝土的强度。
