چکیده مقاله:

Self-compacting concrete (SCC) due to several economical and technical advantages is increasingly used in urban development. It can be improved on strength behavior when the fibers are added. Although the workability must be maintained as a significant factor for this concrete. This investigation experimentally evaluated the effects of recycled PET fibers on the properties of either fresh or hardened SCC. Fresh properties of concrete have been investigated by slump flow, V-funnel and L-box tests. Hardened properties were tested for compressive strength, splitting tensile strength, flexural strength, shrinkage and ultrasonic pulse velocity (UPV) tests. The results showed ۳ Kg/m۳ recycled pet fibers can be considered as suitable contents regarding to fresh and hardened properties of SCC.
