The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the temperature increases due to heat of hydration through all the concrete specimens especially in the control sample. However, the total temperature rises caused by the heat of hydration through both of the new binary and ternary concrete were significantly lower than the control sample. The obtained results reveal that the replacement of Portland cement with binary and ternary materials is beneficial, particularly for mass concrete where thermal cracking due to extreme heat rise is of great concern.

Alkali Activated

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.

The use of pozzolanic materials in the production of concrete for structural purposes is increasing, and this trend is expected to continue, due to technological advancement and the desire for basic structural infrastructure. This paper describes a study undertaken to examine the use of high volume palm oil fuel ash (HVPOFA) as a cement replacement material in concrete, beyond the optimized level of 30%. For this purpose, concrete mixes with 100% ordinary Portland cement (OPC) as control were made, while high volume palm oil fuel ash concrete mixtures were prepared by substituting 50, 60 and 70% of cement by ash at 0.45 water-binder ratio. Mechanical properties of concrete such as compressive, splitting tensile and flexural strength of HVPOFA concrete were studied and compared with that with 100% OPC. The results indicate that palm oil fuel ash of up to 70% by mass can be combined with Portland cement to produce normal strength concrete.

This study was performed to investigate the thermal and mechanical properties of foamed concrete when supplementary cementitious materials (SCMs) are utilized. Sustainable foamed concrete of 1800 kg/m3 dry density was prepared by incorporating Palm Oil Fuel Ash (POFA) ranging from 30 % to 35 % and Eggshell Powder (ESP) from 5 % to 15 % as SCMs. It was found that the combined utilization of POFA and ESP in the foamed concrete produced favorable results by reducing the thermal conductivity up to 42.68 % compared to the control sample, thus enhanced thermal insulating property of foamed concrete. This study confirmed that recycling and reusing of POFA and ESP are possible in foamed concrete which could be used for non-structural applications where thermal insulating is required.
