摘要
碳化及其导致的钢筋锈蚀是影响钢筋混凝土耐久性的重要因素。比较了混凝土表面浸渗、涂料涂覆及浸渗+涂覆复合防护3种表面技术,开展了对混凝土防护的研究。通过碳化试验、紫外/冷凝加速气候老化试验以及混凝土内置钢筋电化学测量等检测手段,研究了3种表面防护技术对混凝土保护性能影响。结果表明,采用硅烷浸渗+水性氟碳涂层的复合浸涂处理,可明显提高钢筋砼结构耐久性。
Concrete carbonation is the important factor influencing the durability of reinforced concrete. By comparing the infiltration, paint coat protection technology, and infiltration ＆ paint coat composite protection technology, the concrete protection was studied. The effect of 3 different surface technologies on concrete was studied through carbonation tests, UV/condensation accelerated aging test and electrochemical test. The results showed that using silane infiltration composite with water-based fluorocarbon coating can significantly improve the durability of concrete structures.
