Early-strength water reducing agent and preparation method thereof
The invention relates to an early-strength water reducing agent and a preparation method thereof, and the early-strength water reducing agent comprises the following raw materials in parts by weight: 25-36 parts of a polyether macromonomer, 3-7 parts of unsaturated acid, 0.05-0.2 part of an initiator, 0.08-0.26 part of a chain transfer agent, 2-4 parts of a pH regulator, 10-18 parts of an early-strength monomer and 42-58 parts of water. The early-strength water reducing agent provided by the invention has relatively good water reducing performance, has good dispersity after being added into concrete, can greatly improve the early compressive strength of the concrete, does not influence the later strength of the concrete, and can effectively shorten the construction progress of the concrete in winter.
本发明涉及一种早强型减水剂及其制备方法，按重量份数计，包括以下原料：25～36份聚醚类大单体、3～7份不饱和酸、0.05～0.2份引发剂、0.08～0.26份链转移剂、2～4份pH调节剂、10～18份早强型单体、以及42～58份水。本发明提供的早强型减水剂，具有较好的减水性能，添加在混凝土中具有分散性好，且能大幅度提高混凝土早期抗压强度，对混凝土后期强度不影响，能有效缩短冬季混凝土施工进度。
