Today, the necessity of environmental awareness and enforcement is more demanding and crucial than ever before. Environmental protection encompasses not only pollution but also sustainable development and conservation of natural resources and the eco-system. As a conclusion, protection and preservation of environment is still a pressing issue. This issue on environmental preservations and sustainability all over the world has lead to innovations of new material using by-products generated from various sectors such as palm oil industry. One of the potential recycle materials from palm oil industry is palm oil fuel ash which contains siliceous compositions and reacted as pozzolans to produce a stronger and denser concrete. Palm oil fuel ash (POFA) is by-product obtained by burning of fibers, shells and empty fruit bunches as fuel in palm oil mill boilers. Apart from POFA, oil palm shell (OPS), which also from oil palm waste has been used as lightweight aggregates resulting from never ending research conducted. In this investigation, these two types of waste were collected from the same palm oil mills in Kuantan, Malaysia and were both utilized inside lightweight aggregate concrete. By incorporating POFA and OPS as partial cement and coarse aggregate replacement, lightweight aggregate concrete with 35 MPa can be produced and is also significantly higher than control OPS concrete.

Palm oil industry is one of the important industry that contribute to the country’s prosperity. This flourishing industry however also causes environmental problems namely air pollution, soil degradation as well as water pollution due to waste disposal issue. At the same time, intensive cement production and granite mining is damaging the environment and natural habitats. Hence, various efforts have been made by researchers to minimize the effect of pollution including integrating oil palm wastes in construction as building materials. In this study, granite aggregate was fully replaced by palm oil clinker (POC) in lightweight aggregate concrete production. In order to reduce the utilization of cement in concrete, palm oil fuel ash (POFA) was ground to improve its pozzolanic reactivity to partially replace cement in lightweight aggregate concrete. From this investigation, the best performance concrete was attributed by POC LWAC with 20% POFA when the water cement ratio and superplasticizer are 0.45 and 1.0%. Inclusion of water cement ratio and superplasticizer of 0.35 and 0.8% would adversely affects the workability and strength of POC LWAC with POFA.

Concern towards reducing waste disposed by Malaysian palm oil industry, palm oil fuel ash (POFA) and oil palm shell (OPS) that poses negative impact to the environment has initiated research on producing oil palm shell lightweight aggregate concrete (OPS LWAC) containing palm oil fuel ash. The present investigation looks into the effect of palm oil fuel ash content as partial cement replacement to compressive strength and acid resistance of oil palm shell lightweight aggregate concrete. Two types of mix, plain OPS LWAC and another one containing POFA as partial cement replacement have been used in this research. Cubes of 100 x 100 x 100 (mm) were water cured for 28 days before subjected to compressive strength test and acid resistance test. The findings indicate that suitable integration of POFA content would ensure occurrence of optimum pozzolanic reaction leading to densification of concrete internal structure which increases the compressive strength and better durability to acid attack. Integration of 20% POFA successfully assist concrete to achieve the highest compressive strength and exhibit superior resistance against acid attack compared to other mixes.

Traditionally fly ash (FA) has been used to replace cement as binder in the geopolymer concrete. The utilization of palm oil industrial waste materials known as palm oil fuel ash (POFA) and oil palm shell (OPS) that are abundantly available in South East Asia as binder and coarse aggregate in geopolymer concrete would give an added advantage in both the environmental and economic aspects. The mechanical properties of the OPS geopolymer concrete (OPSGC) through the use of POFA, FA, and OPS are investigated and reported. A total of ten OPSGC mixtures were prepared with varying percentages of POFA and FA such as 0, 10, 20, 40, and 100%. The specimens prepared with two alkaline solution to binder (AK/B) ratios of 0.35 and 0.55 were oven cured at 65°C for 48 hours. The experimental results showed that the highest compressive strength of 30 MPa was obtained for the mix with 20% replacement of FA by POFA and AK/B ratio of 0.55, which underwent oven curing. Further, the mix of up to 20% POFA (with AK/B ratio of 0.55) can be categorized as structural lightweight concrete. An increase of the POFA content beyond 20% decreases the mechanical properties, and hence this mix is recommended to be used.
