Water reducing agent of alkali slag cementing material and preparation method of water reducing agent
The invention discloses a water reducing agent of an alkali slag cementing material and a preparation method, and belongs to the technical field of concrete admixtures in building materials. The water reducing agent of the alkali slag cementing material takes polyphosphazene as a main chain, side chain substituents are respectively a monomer A, a monomer B and a monomer C, the monomer A is connected with the main chain through hydroxyl in the monomer, the monomer B is connected with the main chain through terminal hydroxyl in the monomer, and the monomer C is connected with the main chain through amino in the monomer; the monomer A is of a polyether long-chain structure; a source monomer of the monomer B is a compound containing hydroxyl or phenolic hydroxyl, and a source monomer of the monomer C is amino acid and a derivative thereof. The water reducer has the advantages that the initial viscosity of freshly mixed alkali slag concrete is reduced, the flowability and workability of the alkali slag concrete are improved, the enhancement effect is obvious, the slump retaining effect is good, the setting time is adjustable and the like, heating is not needed in the preparation process, and energy consumption is reduced.
本发明公开了一种碱矿渣胶凝材料的减水剂及制备方法，属于建筑材料中混凝土外加剂技术领域。所述碱矿渣胶凝材料的减水剂以聚磷腈为主链，侧链取代基分别为单体A、单体B及单体C，所述单体A由单体中的羟基与主链相连，所述单体B由单体中的端羟基与主链相连，所述单体C由单体中的氨基和主链相连；所述单体A为聚醚长链结构；所述单体B的来源单体为含有羟基或酚羟基的化合物，所述单体C的来源单体为氨基酸及其衍生物。该减水剂具有降低新拌碱矿渣混凝土的初始粘度，提高碱矿渣混凝土的流动性和工作性、增强效果明显、保坍效果好、凝结时间可调等优点，制备工艺无需加热，节约能耗。
