摘　　要：在混凝土结构补强中,由于新老混凝土界面粘结能力不足,会严重影响到结构修补后的耐久性和整体性。针对影响新老混凝土粘结性能的主要因素,提出在新混凝土中掺入碳纤维的方法,来改善界面粘结性能。试验证明,这种方法能够大大提高新老混凝土粘结界面的抗剪、抗拉等性能。The improvement of the bond between old and new concrete with carbon fiber concrete is studied in the paper. The durability and integrity of a repaired structure are not enough because of the bad bond between old and new concrete. A method of adding carbon fiber to the new concrete to improve the bond is proposed. The test results show that the shear and tension strength for the interface performance is improved.

关 键 词：碳纤维混凝土 粘结 性能 界面 耐久性
