目前国内尚无以反应性高分子为原材料制成的混凝土减水剂,而国外正处于研究阶段。本文介绍用反应性高分子缓慢释放有分散性的负离子来控制混凝土坍落度损失的原理和方法。
At present, there is no concrete water-reducing agent made of reactive macromolecules as raw materials, and foreign countries are still in the research stage. This article describes the principle and method for controlling concrete slump loss by slowly releasing dispersive negative ions with reactive macromolecules.
