THE EFFECT OF SYNTHETIC FIBER TYPE ON FRESH, HARDENED AND TOUGHNESS PROPERTIES OF HSFR-SCC

This study presents the experimental results about effects of Polyvinyl-alcohol (PVA) and Polypropylene (PP) fibers on fresh mechanical properties including compressive, splitting tensile strength, modulus rupture (MOR) as well toughness hybrid fiber reinforced self-compacting concrete (SCC). PVA PP were added into SCC mixtures having only macro steel also binary hybridization both micro fiber. The showed that use replaced by improved workability, compressive MOR caused reduction in weight loss percentage compared to Moreover, it was emphasized or enhanced residual flexural performance SCC, generally, while negatively influenced workability strengths according single hybridization. Compared effect synthetic fibers, had slightly more positive view more.
