Abstract
There is several agriculture waste materials have continuously been producing. The oil palm shell has been used to produce Oil Palm Shell Concrete (OPSC). And by use of 1% Kenaf-Oil Palm Shell mixture, a natural composite concrete (OPS-kenaf concrete) has been made. The time to failure, stroke and flexural strength of concrete beams have been studied. The concrete cubes have also been tested to identify time to failure and compressive strength of proposed concretes. The results have been indicated that 1% kenaf-OPS mixture enhances flexural strength of beam. And also the stroke and time to failure have not considerably been changed. The significant effect has not been observed on morphology of crack. The compressive strength of (OPS-1% kenaf mixture) has been improved. This new proposed composite concrete beam has acceptable effect on minimizing environment pollution.
Highlights
The possible improvement of the Oil Palm Shell Concrete (OPSC) using natural fibers, such as kenaf fiber is an interesting issue in construction materials and structural engineering
The Oil Palm Shell Reinforced Concrete Beams (OPS_RCB) exhibited higher ductile behavior compared to the beams made of NWC (Shafigh et al, 2011b; Mannan et al, 2002)
Ordinary Portland Cement (OPC), sand, oil palm shell as aggregate and water have been used for casting composite concrete (Fig. 1 and Table 1)
Summary
The possible improvement of the Oil Palm Shell Concrete (OPSC) using natural fibers, such as kenaf fiber is an interesting issue in construction materials and structural engineering.The oil palm shell reinforced concrete has lower bond between oil palm shell and matrix due to concave and convex smooth surface (Mannan and Ganapathy, 2004). The possible improvement of the Oil Palm Shell Concrete (OPSC) using natural fibers, such as kenaf fiber is an interesting issue in construction materials and structural engineering. The OPS has been recommended as a coarse aggregate for the production of low-cost and lightweight concrete (Teo et al, 2006). The Oil Palm Shell Reinforced Concrete Beams (OPS_RCB) exhibited higher ductile behavior compared to the beams made of NWC (Shafigh et al, 2011b; Mannan et al, 2002).
