Abstract

The use of leaflet ribs from oil palm trees - Oil Palm Broom Fibres (OPBF) in reinforcing cement composites have shown some prospects according to recent studies. However, only little is understood regarding their bond interaction with cement matrices. Samples were prepared to investigate the pull-out response of OPBF in both single and combined form from concrete. For the combined fibres, single OPBF strands were wound around one another longitudinally (in helical form) to form tendons. A comparison was made between the maximum bond strengths of untreated and treated OPBF in concrete. The OPBF were pre-treated by soaking in sodium hydroxide and triethylvinylsilane solutions to improve their bond strength with concrete. The reported treatments could improve the potential of OPBF tendons as reinforcement in lightly loaded concrete beams ultimately resulting in an environmentally friendly and affordable construction.
