| 摘 要： | 通过对造纸黑液中木素改性,研究开发了一种新颖的缓凝型混凝土高效减水剂,这种减水剂增强效果略低于萘系高效减水剂,但保坍效果明显好于萘系减水剂,用其配制的高性能混凝土的坍落度可达20cm左右,2h内坍落度损失少于4cm,价格仅为萘系减水剂的1/3～1/2,用其配制的混凝土耐久性能较好.

| Abstract: | A brandnew retardation type concrete high performance water reducing agent has been made through the modification to the lignin in papermaking black liquor. The enhancement effect of this water reducing agent is a little lower than that of naphthalene series high efficiency water reducing agent but its anti-slump effect is better than the latter: the slump of the high performance concrete with this agent can reach 20 cm, and slump loss is less than 4 cm in 2 h. The price of this agent is 1/2 to 1/3 of that of naphthalene series water reducing agent and the lasting quality of the concrete with this agent is better. |
