用无机胶粘贴碳纤维布加固混凝土结构研究现状

Review of Research on Concrete Structures Strengthened with CFRP Sheets Bonded with Inorganic Matrix

摘要: 碳纤维布(CFRP)已广泛应用于土木工程行业,但是所采用的环氧类有机胶的软化点过低。于是国内外学者采用无机胶粘贴碳纤维布加固混凝土结构。本文总结了近年来用无机胶粘贴碳纤维布加固混凝土结构的研究进展，包括材料的力学性能和用无机胶粘贴碳纤维布加固混凝土结构的力学性能。同时指出了无机胶应用过程中存在的问题，并展望了今后的研究发展趋势。

Abstract: Carbon fiber reinforced polymer (CFRP) sheets have been widely used in civil engineering, however the softening points of organic adhesives are too low. So the innovative cementitious materials are used as adhesive for CFRP strengthening systems by scholars. This paper summarizes the progress of research on concrete structures strengthened with CFRP sheets bonded with inorganic matrix, including the mechanical properties of CFRP sheets and the performance of concrete structures strengthened with CFRP sheets bonded with inorganic matrix. Also this paper concludes with the existing problems in the application of inorganic matrix and proposes suggestion for further research.
