摘要
通过高速公路松花江悬索桥工程主塔C5 0级高性能混凝土应用研究 ,介绍在LNC - 5 2型高强混凝土泵送剂中加入SJ- 2型引气剂 ,提高混凝土耐久性 ,尤其是寒冷地区的混凝土抗冻性及抗盐冻性。
C50 high performance concrete(HPC) was applied in the main tower of Songhua river suspended highway bridge.By adding SJ-2 air-entraining agent into LNC-52 pumping agent,the durability,especially the frost resistance in water and sodium chloride solution was improved.
