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.

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.

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.

Induced Changes

The global consumption of aggregate in the construction field is increasing annually, especially in concrete production. With the development of the economy and increase of the population, the demand for concrete and, therefore, a huge amount of aggregate has increased significantly. This issue is pressing and needs to be addressed. Lightweight aggregate (LWA) is one possible solution. This study investigated the potential use of artificial LWA manufactured from alkaline-activated palm oil fuel ash (POFA) with silt due to its properties and performances. Six mixes containing up to 60% silt by total weight combined with optimised activated POFA were analysed. The artificial LWA was synthesised through a pelletising and sintering process at 1150 °C. The increase in the activated POFA proportion in the mixture induced changes in the properties of artificial LWA, including the physical and mechanical properties, durability, and microstructure. The analytical results showed that all of the artificial aggregates were categorised as LWA, based on BS EN 13055. The artificial LWA with 40% activated POFA and 60% silt had the highest crushing strength and acceptable properties for construction applications. This study summarised the performances of the final products and highlighted the different uses of imported silt and POFA as building materials for minimising environmental impacts.

Expanded Shale

Expanded shale lightweight aggregates, as the coarse aggregates, were used to produce lightweight aggregate concrete (LWAC) in this research. At the fixed water-cement ratio, paste quantity, and aggregate volume, the effects of various aggregate gradations on the engineering properties of LWAC were investigated. Comparisons to normal-weight concrete (NWC) made under the same conditions were carried out. From the experimental results, using normal weight aggregates that follow the specification requirements (standard gradation) obtained similar NWC compressive strength to that using uniform-sized aggregates. However, the compressive strength of LWAC made using small uniform-sized aggregates was superior to that made from standard-grade aggregates. This is especially conspicuous under the low water-cement ratio. Even though the workability was affected, this problem could be overcome with developed chemical additive technology. The durability properties of concrete were approximately equal. Therefore, it is suggested that the aggregate gradation requirement of LWAC should be distinct from that of NWC. In high strength LWAC proportioning, following the standard gradation suggested by American Society for Testing and Materials (ASTM) is optional.
