The palm industry in Malaysia is a growing industry as from a mere 400 hectares planted in 1920, the hectarage increased to 5 million hectares in 2011 [1]. A by-product known as palm oil fuel ash (POFA) was a waste from the palm industry. Uncontrolled dumping of POFA give a serious impacts to environmental which creates pollution and health hazard. In this paper, the material characterization of POFA as an additive material to granite residual soil in terms of physical, mineralogical, chemical and mechanical properties has been investigated for the potential usage of the material. Results showed a general improvement of soil sample when mixed with POFA in all physical properties. The domain mineral present in natural soil is kaolinite. The mechanical behaviour also showed an improvement especially when compared to the landfill hydraulic barrier requirements.

Nowadays, an alkali-activated binder has become an emergent sustainable construction material as an alternative to traditional cement and geopolymer binders. However, high drying shrinkage and low durability performance in aggressive environments such as sulphuric acid and sulphate are the main problems of alkali-activated paste, mortar and concrete. Based on these factors, alkali-activated mortar (AAM) binders incorporating high-volume palm oil fuel ash (POFA), ground blast furnace slag (GBFS) and fly ash (FA) were designed to enhance their durability performance against aggressive environments. The compressive strength, drying shrinkage, loss in strength and weight, as well as the microstructures of these AAMs were evaluated after exposure to acid and sulphate solutions. Mortars made with a high volume of POFA showed an improved durability performance with reduced drying shrinkage compared to the control sample. Regarding the resistance against aggressive environments, AAMs with POFA content increasing from 0 to 70% showed a reduced loss in strength from 35 to 9% when subjected to an acid attack, respectively. Additionally, the results indicated that high-volume POFA binders with an increasing FA content as a GBFS replacement could improve the performance of the proposed mortars in terms of durability. It is asserted that POFA can significantly contribute to the cement-free industry, thus mitigating environmental problems such as carbon dioxide emission and landfill risks. Furthermore, the use of POFA can increase the lifespan of construction materials through a reduction in the deterioration resulting from shrinkage problems and aggressive environment attacks.
