Abstract: This paper reports an experimental study of recycled-bottle-PET fibers reinforced concrete. Fiber length was 20mm and volume fraction were 0.05, 0.18 and 0.30%. Flexure and impact tests were performed after 28 and 150 days of curing. Tests at 28 days show that concrete flexural toughness and impact resistance increased with the presence of PET fibers (except for 0.05%). However, at the age of 150 days, this improvement disappeared. This is due to the degradation of the recycled-bottle-PET fibers in the alkaline concrete environment which was visualized by SEM observations.
