摘要
通过多种外加剂的复合，研究了几种以“ＵＮＦ５”为主体的复合外加剂对改善水泥水化性能的复合效应，结果表明，多种外加剂的复合能同时满足混凝土的多种要求，如减水、缓凝、增强、塑化等功效，可使混凝土快速实现脱膜、冬季施工，实现早强高强。
the compound effect of compound admixtures which are maindy composed of UNF5 admixture for modifying the hydration performance of cement is investigated through the compound of several admixtures.The results show that the compounding of several admixtures can meet the requirements of multipre properties such as water reduction, retardation, reinforcement and plastication so as to realize the rapid demoulding and early strengthenign while being in construction in winter.
