Preparation process of concrete containing cellulose water reducer
The invention discloses a preparation process of concrete containing a cellulose water reducer, and relates to the technical field of building materials. When the concrete containing the cellulose water reducer is prepared, oxidized cellulose and alpha-hydroxyl-omega-amino polyethylene glycol react to prepare polyether cellulose; reacting polyether cellulose with cyclic anhydride to obtain a cellulose water reducing agent; the concrete containing the cellulose water reducer is obtained by uniformly mixing the cement, the gravel, the gypsum powder and the cellulose water reducer, adding water and stirring for use, and curing and curing. The cellulose water reducing agent used in the prepared concrete containing the cellulose water reducing agent has good flowability and water reducing effect.
本发明公开了一种含有纤维素减水剂的混凝土的制备工艺，涉及建筑材料技术领域。本发明制备含有纤维素减水剂的混凝土时，先将氧化纤维素和α‑羟基‑ω‑氨基聚乙二醇反应制得聚醚纤维素；将聚醚纤维素和环状酸酐反应制得纤维素减水剂；将水泥、沙石、石膏粉、纤维素减水剂混合均匀加水搅拌后使用，固化养护后即得含有纤维素减水剂的混凝土。本发明制备的含有纤维素减水剂的混凝土所使用的纤维素减水剂具有良好的流动性和减水效果。
