Experimental Research on Flexural Behavior of Recycled Concrete One-Way Slab Reinforced with CFRP

This paper is supported by National 863 Plans Projects and Sub-project of Science and Technology Department of Sichuan Province, through experimental research on flexural behavior of non-crack recycled concrete one-way slabs reinforced with CFRP, research the ultimate bearing capacity and maximum deflection of it, and comparative analysis the results with recycled concrete one-way slabs which is not been reinforced and reinforced with CFRP after post-cracking. The results show that, the ultimate bearing capacity is higher than the non-crack reinforced concrete slabs, at the same time the deflection is smaller. The ultimate bearing capacity of non-crack recycled concrete one-way slab reinforced with CFRP is lower than post-cracking recycled concrete one-way slab reinforced with CFRP, at the same time the deflection is greater. But found bearing capacity and deflection is lower than that post-cracking recycled concrete one-way slab reinforced with CFRP when experimental on flexural behavior of non-crack recycled concrete one-way slabs reinforced with CFRP, and do a preliminary analysis for this phenomenon.
