This research showed the results of experiments effect use of oil palm fibre (OPF) from oil palm industry as partial replacement for ordinary Portland cement. Research on the reuse of waste materials in the concrete industry has been quite intensive in the past decade. The objective of this research is to identify the Effect of oil palm fibre as a partial cement replacement in the production of concrete. After the treatment, the economical ways to dispose of it is by using landfill method. But due to a limited landfill site in Malaysia and it is the temporary solution for the disposal of the waste, it becomes a problem to Malaysia and the number of the oil palm fibre keeping increase year by year because of the population increase year by year too. The results showed that oil palm fibre (OPF) greatly improved the compressive and flexural strength of concrete. The rate of water absorption of oil palm fibre (OPF) concrete was reduced as oil palm fibre filled up the existing voids, making it more impermeable. However, the compressive strength of the oil palm fibre concrete decreases gradually when the amount of oil palm fibre (OPF) increased. It can be concluded that the optimum percentage of oil palm fibre as a partial cement replacement is 10%. In this direction, an experimental investigation of ultrasonic pulse velocity, carbonation test, compressive strength, flexural strength and water absorption was undertaken to use oil palm fiber and admixtures as partial replacement for cement in concrete.

This paper presents the experimental results of an on-going research project on geopolymer lightweight concrete using two locally available waste materials—low calcium fly ash (FA) and oil palm shell (OPS)—as the binder and lightweight coarse aggregate, respectively. OPS was pretreated with three different alkaline solutions of sodium hydroxide (NaOH), potassium hydroxide, and sodium silicate as well as polyvinyl alcohol (PVA) for 30 days; afterwards, oil palm shell geopolymer lightweight concrete (OPSGPC) was cast by using both pretreated and untreated OPSs. The effect of these solutions on the water absorption of OPS, and the development of compressive strength in different curing conditions of OPSGPC produced by pretreated OPS were investigated; subsequently the influence of NaOH concentration, alkaline solution to FA ratio (A/FA), and different curing regimes on the compressive strength and density of OPSGPC produced by untreated OPS was inspected. The 24-hour water absorption value for OPS pretreated with 20% and 50% PVA solution was about 4% compared to 23% for untreated OPS. OPSGPC produced from OPS treated with 50% PVA solution produced the highest compressive strength of about 30 MPa in ambient cured condition. The pretreatment with alkaline solution did not have a significant positive effect on the water absorption of OPS aggregate and the compressive strength of OPSGPC. The result revealed that a maximum compressive strength of 32 MPa could be obtained at a temperature of 65°C and curing period of 4 days. This investigation also found that an A/FA ratio of 0.45 has the optimum amount of alkaline liquid and it resulted in the highest level of compressive strength.

In this study, the effects of heat-treated and non-treated oil palm shell (OPS) species (dura and tenera) are investigated on the slump, density and compressive strength of oil palm shell concrete (OPSC). Two different species of OPS coarse aggregates are subjected to heat treatment at 65 and 130 °C with the duration of 1 h. The results show that the workability of the OPSC increases significantly with an increase in temperature of heat-treated of the tenera OPS aggregates. It is found that the maximum achievable 28-days and 180-days compressive strength is 51 and 54 MPa, respectively. Furthermore, rapid chloride penetration tests (RCPT), porosity measurement and water absorption tests were performance to signify the effects of heat treatment on different OPS species lightweight concrete (LWC). The use of heat-treated OPS LWC induced the advantageous of reducing the permeability and capillary porosity as well as water absorption. The results showed that the ideal of heat treatment method has enhanced the performance of drying shrinkage. Hence, the findings of this study are of primary importance as they revealed that the heat treatment on OPS species LWC can be used as a new environmentally friendly method to enhance the durability properties and drying shrinkage of OPS LWC.

Oil Palm Shell

Recycling and reusing waste materials as aggregate replacement play an important role in solving issues associated with environmental problems and depletion of non-renewable resources. The use of these waste materials as aggregate is highly desirable as it can serve to sanitise the environment and create cheaper, renewable aggregates which will provide a double advantage as cost effective construction material and waste disposal at the same time. Hence, there is growing interest in this research area to promote safe and economical use of waste material as aggregate alternative in concrete. In Malaysia, where oil palm shell (OPS) is generated in abundance from the oil palm industry, reusing OPS as concrete aggregate replacement has been widely studied. Results from previous studies have shown that OPS concrete can be used in practical application as structural lightweight concrete. However, the properties of OPS can be further improved to achieve better performance of the resulting concrete. Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer which is extensively used in all kinds of industries, such as papermaking, adhesive for plywood, printing and even in the construction industry as internal wall coating, plasterwork and joint sealing. It has been found that PVA has the potential to improve the quality of the OPS aggregates and hence enhance the resulting concrete properties. In this paper, an experimental program on concrete produced from PVA coated OPS aggregates is presented. The PVA treated OPS concrete was tested for slump, air-dry density, compressive strength, and water absorption. It was found that PVA treated OPS concrete had significant improvement in its compressive strength as compared to raw OPS concrete. It was determined that PVA treated OPS concrete can achieve 28-day compressive strength of up to 33.53 MPa. Moreover, it was also determined that there was a decrease of 0.67% in the water absorption of PVA treated OPS concrete as compared to the raw OPS concrete. In general, the investigation results showed that PVA can be used to improve the OPS concrete properties for the production of structural lightweight concrete.
