混凝土中的钢筋阻锈性能试验研究

The Experiment and Study of Reinforcing Bar Anti-rust Performance in the Concrete

混凝土中钢筋的锈蚀是钢筋混凝土结构物耐久性的一个突出问题 .本次试验是根据新建地方铁路德—龙—烟线大家洼至莱州段滨临渤海 ,部分线路环盐田行进 ,环境水具有以Cl-为主 ,伴有SO2 -4 、Mg2 + 共存综合侵蚀且指标超常的特殊情况 ,而研制了WQ防腐阻锈剂来解决工程实际问题 .

A projecting problem of reinforced concrete construction durability is rust of the reinforcing bar. According to Daxiangwa to Laizhou section of the newly built railway De-Long-Yan line, This experiment was done. This section gets close to Bohai and part of the line extends to salt pan. The water in this environment is in a special extra-index condition which is mainly composed of Cl - and accompanied by SO 2- 4、Mg 2+ coexisting. Putting the above together, we developed WQ anti-rust preservative to slove this practical problem in the project.
