AF 型减水剂(以下简称 AF)是建筑材料科学研究院等单位最近研制的一种以多环芳烃为主要原料的低引气型高效减水剂,来源丰富,成本较低,有利于推广使用。本文研究了 AF 的适宜掺量、掺加技术,并介绍了 AF 对国内十三个水泥厂生产的十六种水泥的适应性、塑化功能、减水增强功能、节省水泥功能及与早强剂复合的效果。本文还对国产的十三种减水剂的技术经济效果作了
AF type water reducing agent (hereinafter abbreviated as AF) is a low bleed-type superplasticizer based on polycyclic aromatic hydrocarbons recently developed by the Institute of Building Materials Science and other institutes. The source is abundant and the cost is low, which is conducive to promotion. use. In this paper, we studied the appropriate dosage and technology of AF, and introduced AF’s adaptability, plasticization function, water-reducing enhancement function, cement-saving function, and early strength of 16 kinds of cement produced in 13 domestic cement plants. The effect of compounding. This article also made a technical and economical effect on thirteen domestic water reducers.
