碳纤维加固形式对混凝土柱耐久性影响的试验研究

Experimental investigation of influence of carbon fiber reinforcing methods on durability of concrete column

针对碳纤维加固混凝土构件在海洋环境下的耐久性性能进行研究.在人工海洋环境下,进行碳纤维加固混凝土短柱的耐久性试验.试验结果表明采用碳纤维加固提高混凝土短柱的耐久性性能是可行的,加固后的混凝土短柱的耐久性指标都得到了不同程度的提高,不同的加固防护形式对混凝土短柱的耐久性指标有较大的影响.

Investigation of durability of concrete components reinforced with carbon fiber and located in marine environment was conducted. A stump of concrete reinforced with carbon fiber was tested in artificial marine environment. The test result showed that it was feasible to improve the durability of concrete stump by reinforcing it with carbon fiber, the durability index of so reinforced concrete stump was improved to some extent, and different reinforcement methods had greater influence on the durability index of concrete stump.
