【摘要】 由分子设计的原则,从减水剂的分子结构和引入官能团入手,对三聚氰胺系高效减水剂进行了系统合成。与亚硫酸氢钠做磺化剂所得减水剂比较,改性后减水剂的减水率及混凝土强度有明显提高。更多还原

【Abstract】 Melamine superplasticizer was synthesized methodically, beginning with its moleculer structure and introduction of functional groups, correlating with molecular structure characteristics. Compared with common melamines superplasticizer, the modified melamine superplasticizer has much higher water reduction and even better strengthening performance.更多还原
