Polyethylene terephthalate (PET) fibers have been used in fiber reinforced concrete, but poor dispensability of PET, due to low wettability, cause reduce strength of the fiber reinforced concrete. However, the hydrophobic nature of PET surface results poor wettability with ionic surface of cement, sand and other concrete admixture, proper bonding between the hydrophobic PET and hydrophilic cement matrix is possible with surface modification of polyester fiber. In present work attempt to modify the PET fiber surface by chemical treatment at ambient temperature and see the effects on compressive strength, split tensile strength and flexural strength. A comparison will be drawn between all these materials. In this project treated polyester fiber was used to prepare fiber reinforced concrete. The polyester fiber was used at different percentages (0%, 0.20%, 0.25%, & 0.30%) by weight of cement and comparison of strength of concrete for treated fiber reinforced concrete at different percentage was carried out. The concrete samples were prepared (cube, cylinder & beam) and cured in normal water for 7, 28 and 56 days. The study was carried out to see the effect of acidic rain on fiber reinforced concrete. Acidic water was prepared by using the concentrated HCl in deionized water respectively. To see the environmental effect, the Concrete samples were cured in acidic for 56 days. The samples were tested for compressive strength, split tensile strength and flexural strength and found that 0.25% of PET fiber by weight of cement may be recommended for optimum dose. The studies indicate that the dispersion of treated fiber in concrete was better with respect to normal fiber. The fiber reinforced concrete was also more resistance against acidic environment with respect to normal concrete. In all aspects, the treated fibre reinforced concrete was found better than normal reinforced concrete.
