Abstract:
Palm oil fuel ash obtained from palm oil mill was treated via screening, grinding and heating to improve its pozzolanic reactivity. The characteristics of the palm oil fuel ash before and after treatment were monitored to assess the changes in the properties of the palm oil fuel ash. The resulting ultrafine palm oil fuel ash was then utilized to produce high strength concrete by replacing the ordinary Portland cement at 0, 20, 40 and 60% on mass-for-mass basis. The results show that the treatment process undertaken reduces the particle size, diminishes the unburned carbon content, while at the

In this work, the potential beneficial uses of palm oil fly ash (POFA) as a green pigment in paint technology via sintering process was studied. The POFA composites were sintered in the furnace at temperature 750°C. The obtained green pigment from POFA composites through the processes of mixing, reductive heating, ball milling and sieving was subsequently characterized by X-Ray diffraction technique.

Self Compacting Concrete (SCC) is a new innovation in technology that can flow readily into place under its own self weight and fill corner areas of reinforcement structures without the need to vibrate and without segregation of its constitute. The problem of durability of concrete structures due to inadequate compaction by skilled workers has become a source of concern globally. The shortage of skilled manpower, noise and vibration of equipment on construction sites has led to the development of self compacting concrete.

Abstract:
In this paper, the effect of different curing methods on the strength of concrete with palm oil fuel ash as a cement replacement is investigated. An experimental program was carried out to study the effect of five different curing methods, i.e., water curing (WC), air curing (AC), plastic-wrapped curing (PC), oven and water curing (OWC), and oven and air curing (OAC), on the compressive and flexural strengths of palm oil fuel ash concrete (POFA20), where 20% of the cement was replaced by palm oil fuel ash. The results obtained from this investigation showed that POFA20-WC has the highest compr

Abstract:
Geopolymer is a cement free material which uses binder produced by the reaction of the alkaline liquid solution with binding agents. In this study, the performance of geopolymer mortar using Palm Oil Fuel Ash (POFA) and Rice Husk Ash (RHA) as binding agents was carried out. The tests conducted in this research were Specific Gravity, X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), bulk density and compressive strength at 7th, 14th and 28th days. The results show both POFA and RHA materials fulfilled the criteria as a pozzolanic material. Meanwhile, the cement based mortar has the h

Abstract:
Blended concrete has later strength development with long maturity strength development. An accelerator is thus needed to enhance the early strength development of concrete. This paper shows the combination of ground palm oil fuel ash and eggshell powder that was designed for later and early strength development, respectively. Two types of eggshell powder were utilised in concrete: uncarbonised eggshell powder and decarbonised eggshell powder. The study was initiated with compression test for concrete curing at age 1, 3, 7, and 28 days followed by rapid evaluation test of setting time to inves

Abstract:
Nowadays, waste products such as Palm Oil Fuel Ash (POFA) and Oil Palm Shell (OPS) are produced in large quantities from the agriculture industry on a daily basis. Improper disposal of the agriculture wastes at landfills contributes to environmental pollution. The cost of construction material increases when the demand is high. Therefore, reutilization of these waste products not only reduces the cost of construction material but also minimizes waste disposal problem. In this research, waste POFA and OPS as cement and aggregate replacement respectively are used to produce a ?greener? concrete.
