Enhancement of polypropylene twisted bundle fiber on the mechanical properties of high strength oil palm shell lightweight concrete
This paper presents the results to compare the effect of polypropylene twisted bundle (PPTB) fibers in enhancing the mechanical properties of oil palm shell fiber-reinforced concrete (OPSFRC). The volume fraction (Vf) of 0.125%, 0.25%, 0.375% and 0.5% were studied for each fiber. As PPTB fibers we...

| description | This paper presents the results to compare the effect of polypropylene twisted bundle (PPTB) fibers
in enhancing the mechanical properties of oil palm shell fiber-reinforced concrete (OPSFRC). The volume
fraction (Vf) of 0.125%, 0.25%, 0.375% and 0.5% were studied for each fiber. As PPTB fibers were added into
OPSFRC, the density reduction without reducing strength was reported. The results indicate that an increase in
PPTB fiber decreased the workability. All the mixes reinforced with PPTB fibers improved significantly in
mechanical properties. The 28 day compressive strength of PPTB fiber OPS high strength lightweight concrete
(HSL WC) in continuously moist c~ring was in the range of 42-47 MPa. The splitting tensile/compressive
strength and the flexural/compressive strength ratio of plam OPS concrete are comparable with artificial
lightweight aggregate. An increase in the post-failure compre~sive toug~ness of OPSFRC of up to 29 % was
reported in mixes reinforced with PPTB fiber. ~ence, the findmgs of this study reveal that PPTB fiber can be
used as an alternative material to reduce the density as well as to enhance HSL WC. |
