Experiment Research on RC Slab Strengthened with CFRP Grid/Cao Rui,Yue Qingrui(Research Institute of Building and Construction MCC Group, Beijing 100088,China)
Abstract:A new reinforcement technique with a kind of carbonfiberreinforcedplastic produced as a two or threedimensional grid is adopted.According to comparative experiments on slabs reinforced with different grids, mechanical properties of reinforced slabs are investigated, and the experiment results are compared with those of slabsreinforced with carbonfibersheet.The experiment results indicate that the property of reinforced slab is greatly improved.
