聚羧酸高性能减水剂在泰州长江大桥大体积沉井中的应用

Application of polyocarboxy acid high performance water reducing agent to mass caisson of Taizhou Yangtze River Bridge

泰州长江大桥作为在国内首次采用三塔两跨悬索结构的桥梁,设计中对混凝土工程的施工质量提出了很高的要求。减水剂是控制混凝土施工质量的重要因素,试验及工程实际应用表明,HLC-Ⅸ聚羧酸高性能减水剂与胶凝材料的适应性好,使用HLC-Ⅸ能配制出适合不同工程条件要求的混凝土。

Taizhou Yangtze River Bridge,as domestic bridge firstly of construction quality is quite high in the design of concrete works. using three tower two span suspension structure,its demand Water reducing agent is an important factor in the quality control of concrete construction. Tests and engineering practice show that HLC-Ⅸ polyocarboxy acid high performance water reducing agent adapts to cementing materials well. HLC-Ⅸ can be used to make suitable concrete for different engineering conditions.
