Effect of Different Percentages of Waste High Density Polyethylene (HDPE) Fibres on the Properties of Fibre Reinforced Concrete

摘要

Most of HDPE fibre become waste after their usage, causing environmental problems. To address this issue, a method to recycle waste High Density Polyethylene (HDPE) fibre is presented to investigate the possibility of using various plastic wastes containing HDPE fibre as polymer additives to concrete. The experimental investigation is carried out to verify the effect of different percentages of waste HDPE fibres on the workability and strength characteristics of fiber reinforced concrete. Appropriate tests were performed to measure different strength characteristics like compressive strength, tensile strength, flexural strength and impact strength on different percentages of waste HDPE fibres like 0%, 0.2%, 0.4%, 0.6%, 0.8% and 1 %. The results show that how compressive strength increases up to certain percentage and decreases as fiber volume fraction is increased.
