| 摘 要： | 研究了纤维增强聚合物(fiber reinforced polymer/plastic,FRP)加固锈蚀混凝土结构抗腐蚀特性,并与2种常用的阻锈材料(硅烷和Sika903)进行了比较.试验研究了FRP种类(碳纤维布(carbon fiber reinforced poly-mer/plastic,CFRP)、玄武岩纤维布(basalt fiber reinforced polymer/plastic,BFRP)和聚乙烯纤维布(polyethylenefiber reinforced polymer/plastic,PEFRP))、环氧树脂对阻锈性能的影响,试验研究表明:几种阻锈材料表现出不同的阻锈能力,CFRP、BFRP和PEFRP加固试件的理论锈蚀率(由实测的腐蚀电流确定)分别是标准试件(未保护试件)的13.9%、23.6%和17.2%;硅烷保护试件的理论锈蚀率与FRP系列差别不大,是标准试件的22.5%;Sika903阻锈蚀能力稍差,理论锈蚀率是标准试件的44.3%;单独使用环氧树脂可以取得良好的阻锈效果,理论锈蚀率是标准试件的20.7%.

| Abstract: | Fiber reinforced polymer/plastic(FRP) being relatively watertight and airtight can resist corroding.This paper researches the resistance to corrosion of reinforced concrete structure retrofitted with FRP.The differences of anticorrosion performances between FRP and two common anticorrosion materials(silicon alkyl and Sika903)are compared.The influence on the anticorrosion performances of reinforced concrete structure retrofitted with different types of FRP and the epoxy is analyzed.Results show that the rus... |
