High-performance concrete water reducing agent and preparation method thereof
The invention discloses a high-performance concrete water reducing agent and a preparation method thereof, and belongs to the field of concrete water reducing agents. The water reducing agent comprises the following raw materials: a sulfamate water reducing agent, a naphthalene water reducing agent and an acetone dispersion liquid of swollen sulfonated lignite in a mass ratio of (14-16): (5.5-6.5): (520-680). The water reducing agent can improve the fluidity of neat paste, the water reducing agent is added according to the dosage of 0.65 wt% of cement, the fluidity of the neat paste is tested according to a method in GB/T 8077-2012, and the fluidity of the neat paste is 262-275 mm.
本发明公开一种高性能混凝土减水剂及其制备方法，属于混凝土减水剂领域。所述减水剂的原料包括氨基磺酸盐减水剂、萘系减水剂、溶胀磺化褐煤的丙酮分散液，质量比为14‑16:5.5‑6.5:520‑680。本发明的减水剂可以提高净浆流动度，将本发明的减水剂按照掺量为水泥用量的0.65wt%进行添加，并按照GB/T 8077‑2012中的方法测试净浆流动度，净浆流动度为262‑275mm。
