This paper reports the results on deflection behaviour of reinforced concrete (RC) beam conducted using irregular-shaped Polyethylene Terephthalate (IPET) as a fibre. Three volume fraction of IPET fibre is used namely, 0.5%, 1% and 1.5%. All RC beam specimens are tested under four point loading under flexural capacity behaviour. The results for deflection behaviour namely cracking stage, yield stage and ultimate stage and ductility are reported. The results than are compared with control RC beam. It is found that the addition of IPET fibre improves the first crack and ultimate strength as well as ductility of RC beams proportional to the increment of volume fraction of IPET fibre. Therefore, based on the results reported, the addition of IPET fibre significantly increases the deflection behaviour of RC beam.
