Cement grinding aid composition and chlorine-free liquid cement grinding aid containing same
The invention relates to a cement grinding aid composition and a chloride-free liquid cement grinding aid containing the composition, the cement grinding aid composition comprises an alcohol amine-carboxylic acid polymer and sodium thiocyanate, and the mass ratio of the alcohol amine-carboxylic acid polymer to the sodium thiocyanate is 1: (0.5-4). The cement grinding aid provided by the invention can effectively improve the utilization rate of cement raw materials, reduce the use amount of clinker, improve the fluidity of cement and improve the workability of cement. Meanwhile, the cement grinding aid disclosed by the invention does not contain chloride ions, so that the service life of concrete is not influenced.
本发明涉及一种水泥助磨剂组合物及包含该组合物的无氯液体水泥助磨剂，所述水泥助磨剂组合物包括醇胺‑羧酸系聚合物和硫氰酸钠，其中所述醇胺‑羧酸系聚合物和硫氰酸钠的质量比为1:0.5‑4。本发明的水泥助磨剂可以有效提高水泥原料的利用率，降低熟料用量，还能提高水泥的流动度，提供水泥的工作性。同时，本发明的水泥助磨剂不含有氯离子，不会影响混凝土的使用寿命。
