BEHAVIOR OF RECYCLED AGGREGATE CONCRETE BEAMS STRENGTHENED WITH FRP
Keywords:Recycled Aggregate Concrete, Carbon fiber polymer sheet
In this paper, the experimental work of this research included the test of seven concrete beams with dimensions (0.24 * 0.15 * 1.7) m. The mixing ratio is (1:2:3) and the water ratio(w/c) is 0.5. The first control beam has new aggregates and without strengthen with carbon fiber polymer sheet. The next three beams have the different ratio of recycled aggregate of (25%, 50%, 75%), and the last three beams have the different ratio of recycled aggregate of (25%, 50%, 75%) and with strengthen with carbon fiber polymer sheet. The experimental results showed that the ultimate load in the control beam (NC) became approximately (4,9,14) % respectively higher than the group of the recycle aggregate (B2. B3. B4) beams. When strengthening the beams by carbon fiber polymer sheet. The author notice the ultimate load in the control beam (NC) became approximately (20,16,0) % respectively lesser than the group of recycle aggregate (B5.B6.B7) strengthening beams.
