| 摘 要： | 碳纤维复合材料(CFRP)具有不透水和不透气的性质,是一种阻锈材料;同时具有高强度和优异的耐腐蚀能力,可用于加固维护处于腐蚀环境的钢筋混凝土结构.本文试验研究了CFRP加固锈蚀钢筋混凝土试件再次受到腐蚀作用时的抗腐蚀能力和黏结性能,并与传统的防腐维护材料(硅烷和聚合砂浆)进行了对比.试验研究表明:CFRP不仅能阻止混凝土中钢筋的进一步锈蚀,并且能提高锈蚀钢筋与混凝土之间的黏结强度.

| Abstract: | Carbon Fiber Reinforced Polymer/Plastic ( CFRP) can resist corroding because they are relatively watertight and airtight. CFRP can be used to strengthen the reinforced concrete structure because of its high strength and good corrosion resistance. This test will research the corrosion resistance and bond strength of corrosion-reinforced concrete wrapped CFRP subjected to corrosion again. The differences between CFRP and the conventional protective systems ( silicon alkyl and polymer mortar ) were discussed i... |
