Abstract:CFRP has found wide applications in the field of strengthening of concrete structures due to its remarkable fea?tures, such as high strength, light weight, anti-corrosion and duration. The construction method is the key factor in full ex?erting the advantages of carbon fiber sheet to achieve and guarantee the best strengthening effect. This article mainly intro?duces the construction feather and performance of material and method of using carbon fiber sheet in strengthening.
