| Summary: | 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. |
