Cement retarder composition and preparation method thereof
The invention discloses a cement retarder composition and a preparation method thereof, and belongs to the technical field of concrete admixtures, the cement retarder composition comprises 12-15 parts of a polycarboxylate superplasticizer, 8-10 parts of a quaternary ammonium salt type cationic polymer, 2-5 parts of triethanolamine, 1-2 parts of liquid water glass, 20-25 parts of zinc hydroxide powder, and 25-30 parts of an ice-water mixture. The cement retarder composition provided by the invention can improve the retarding performance of the polycarboxylate superplasticizer, so that the hydration of cement particles is further slowly carried out.
本发明公开了一种水泥缓凝剂组合物及其制备方法，属于混凝土外加剂技术领域，该水泥缓凝剂组合物包括聚羧酸高效减水剂12～15份、季铵盐型阳离子聚合物8～10份、三乙醇胺2～5份、液体水玻璃1～2份、氢氧化锌粉末20～25份、冰水混合物25～30份。本发明的水泥缓凝剂组合物能够改善聚羧酸减水剂的缓凝性能，使水泥颗粒的水化进一步地缓慢进行。
