采用聚羧酸减水剂、有机胺和无机盐复配了聚羧酸系泵送剂。该泵送剂减水效果好,60min无坍落度损失,对混凝土促强作用明显。使用该泵送剂的混凝土拌合物工作性能优异,与各种水泥相容。 The use of polycarboxylate superplasticizer, organic amine and inorganic salts with polycarboxylic pumping agent. The pumping water reducing effect is good, no slump loss 60min, the role of concrete to enhance the obvious. Concrete mixes using this pumping agent work well and are compatible with a variety of cements.
