Abstract
Within the development of Malaysia, demand of concrete increasing gradually from time to time through continuously development of infrastructure. The uses of sand as fine aggregate in the production of concrete has become excessive. New research has been up by using oil palm frond to replace sand in the concrete mixture. This research was conducted to investigate workability and strength of concrete with oil palm frond as partial fine aggregate replacement. The oil palm frond is grind into smaller size suitable to sand’s size as it be used as partial fine aggregate replacement. For this research, different percentage which are 0%, 2.5%, 5.0%, and 7.5% of oil palm frond was used as partial fine aggregate replacement to produce various type of mixes. All concrete was design to grade C25/30. Then, all samples were cured for 7, 14 and 28 days in the water tank. Slump test was conducted to determine the workability of fresh concrete while compressive strength test and flexural test were conducted to determine the strength of hardened concrete. Results show that, the compressive strength of 0%, 2.5%, 5.0% and 7.5% fine aggregate replacement achieved the compressive strength of 38.02, 26.34, 24.89 and 19.33 N/mm2, respectively at 28 days. Meanwhile, for flexural strength results show that after the fine aggregate replacement it achieved 35.33, 22.17, 19.71, and 16.81 N/mm2, respectively for replacement of 0%, 2.5%, 5.0% and 7.5%. Findings showed that the optimum percentage of fine aggregate replacement was 2.5%. These results show that oil palm frond concrete can be used as fine aggregate replacement in which reduced cost and eco-friendly. At the same time, uses of OPF as partial fine aggregate replacement in concrete would reduce the high dependency on natural fine aggregate and offering alternatives to preserve natural sand for the use of future generation.
