摘      要：Polyethylene terephthalate bottles production has drastically increased year after year due to high versatility of polyethylene terephthalate plastics and considerable consumption of *** tandem with that increase,the major concern of society has been the improper disposal of this non-biodegradable material to the *** deal with this concern,recycled polyethylene terephthalate bottles were incorporated in concrete as fibre reinforcements in this *** objective of this research is to evaluate the mechanical properties of recycled polyethylene terephthalate fibre reinforced concrete(RPFRC)in comparison with control concrete without *** terephthalate fibres with three different diameters(0.45,0.65,and 1.0 mm)and two lengths(20 and 30 mm)were added at various proportions(0.5%,1.0%,1.5%and 2.0%)by volume of concrete in order to determine the effect of fibres initially on compressive,flexural and splitting tensile strengths of *** results revealed that none of the fibres have detrimental effects up to 1%volume fraction,however further addition caused slight reductions on mechanical properties in some *** shrinkage resistance and impact resistance tests were also performed according to related *** terephthalate fibres were observed to have marked improvements on those *** a good performance could be attributed primarily to the bridging effect of fibres.
