水工混凝土复合型高效减水剂试验研究

Testing and Studying the Composite High-efficiency Water-reducing Agent for Hydraulic Concrete

随着水利工程建设的快速发展,为了满足工程建设对集多功能于一身的高效减水剂的需求,通过试验研究,成功配制了JSNJ-2缓凝高效减水剂和JSNJ-3早强高效减水剂。经检测各项指标符合国标要求,可在施工难度高、技术要求复杂的工程中使用,起到复合高效减水剂高效经济的作用。

In pace with the high-speed development of hydraulic engineering,in order to meet the construction demand,there is a need to make a kind of high-efficiency agent which must gather the multi-functions in one body.For this reason two kinds of water-reducing agents： the retarding high-efficiency water-reducing agent JSNJ-2 and the early-strength high-efficiency water-reducing agent JSNJ-3 have been tested,studied and have been made up successfully.Through examining,their each index has met the demand of national standard.In difficult and complex engineering,they can be used and will play economic,high-efficiency water-reducing effect.
