掺加矿渣微粉对C55混凝土耐久性影响分析

Analysis on the impacts of mixing grounded furnace slay on C55 concrete durability

针对目前普遍存在的混凝土耐久性问题,分析了影响C55高性能混凝土耐久性的主导因素,以重庆嘉华嘉陵江大桥为工程实例,着重论述了掺加矿渣微粉对混凝土的碳化、渗透耐久性的影响,并提出了提高混凝土耐久性的措施,以期延长混凝土使用寿命。

In light of common existing concrete durability issue, this paper analyzes the main factors influencing C55 high-strength concrete du- rability. Taking Jialing river Bridge in Jiahua of Chongqing as engineering example, it mainly discusses the impacts of mixing grounded furnace slay on the concrete carbonization and penetrating durability, and proposes measures to improve concrete durability, with a view to prolong the life expectancy of concrete.
