Water reducing agent for high-strength concrete and preparation method thereof
The invention belongs to the technical field of concrete admixtures, in particular to a high-strength concrete water reducer and a preparation method thereof. The problems of complex preparation process and high cost of the high-performance water reducing agent and high viscosity and poor volume stability of concrete in the prior art are solved; the water reducing agent for the high-strength concrete is prepared from the following raw materials: acrylic acid, a chain transfer agent, ammonium persulfate, methoxy polyethylene glycol, polyethylene glycol ether, 1,3-dimethylimidazole methyl sulfate, sucrose fatty acid ester, carbon fiber powder, a defoaming agent and sodium hydroxide. The water reducing agent prepared by the invention has high water reducing rate and good fluidity and permeability; the concrete admixture has the advantages of low consumption, obvious improvement of the dispersion effect of concrete particles, improvement of the bonding strength among the concrete particles, improvement of the mechanical properties and the mechanical properties of concrete, and good wear resistance and corrosion resistance.
本发明属于混凝土外加剂技术领域，尤其是一种高强混凝土用减水剂及其制备方法，解决了现有技术高性能减水剂制作工艺复杂、成本高，且无法解决混凝土粘度大、体积稳定性差等问题，所述高强混凝土用减水剂，包括以下原料：丙烯酸、链转移剂、过硫酸铵、甲氧基聚乙二醇、聚乙二醇醚、1,3‑二甲基咪唑硫酸甲酯盐、蔗糖脂肪酸酯、碳纤维粉、消泡剂、氢氧化钠。本发明制得的减水剂具有高的减水率、良好的流动性和渗透性；其作为混凝土的外加剂用量少，能显著改善混凝土颗粒的分散作用，提高混凝土粒子间的结合强度，进而提高混凝土的力学性能和机械性能，使其具有良好的抗磨损性和抗腐蚀性。
