Flexural Performance of Reinforced Concrete Beams Strengthened With Double Vertical Carbon Fiber Reinforced Polymer (CFRP) Plate Using Near Surface Mounted (NSM)
Three reinforced concrete beams were prepared with the same size which is 150 mm × 300 mm and 1800 mm as length with the concrete strength of 30 N/mm2. The research was carried out to evaluate the flexural perfor- mance of reinforced concrete beam strengthened with
Carbon Fiber Reinforced Polymer (CFRP) plate, when immersed into salt water. The project tested three different beams. The first beam was a normal rectangular reinforced concrete beam function as control. The second beam and third beam were reinforced concrete beams that were strengthened
with double vertical Carbon Fiber Reinforced Polymer (CFRP) plates. The reinforced concrete beams were strengthened using Carbon Fiber Reinforced Polymer (CFRP) curing at normal 28 days and immersed into the salt water for 28 days respectively. The result shows that the beam strengthening
with CFRP plate can increase the flexural performance of the beam by 10%. The good performance of tension of CFRP double vertical plates has enhanced the performance of the beam and it can sustain a maximum load of 123.94 KN compared two other specimens.
