Polycarboxylate superplasticizer composition
The invention discloses a polycarboxylate superplasticizer composition, and relates to the technical field of cement additives. The composition comprises a polycarboxylic acid water reducing agent, glycerol triglycidyl ether and diethylene glycol acid, wherein the polycarboxylate superplasticizer is prepared from the following raw materials in parts by mole: 10 parts of acrylic acid or methacrylic acid, 4 to 6 parts of unsaturated polyether and 2 to 4 parts of 2-methyl-2-acrylic acid-2-hydroxyethyl phosphate. The polycarboxylate superplasticizer composition disclosed by the invention has relatively good mud resistance and relatively low bleeding rate, and meanwhile, the early strength of concrete can be improved.
本发明公开了一种聚羧酸减水剂组合物，涉及水泥添加剂技术领域。该组合物包括：聚羧酸减水剂、甘油三缩水甘油醚、一缩二乙二醇酸；其中，以摩尔份计，所述聚羧酸减水剂的原料包括：10份丙烯酸或甲基丙烯酸，4~6份不饱和聚醚、2~4份2‑甲基‑2‑丙烯酸‑2‑羟乙基酯磷酸酯。本发明的聚羧酸减水剂组合物，其具有较好的抗泥性能和较低的泌水率，同时能够增加混凝土的早期强度。
