Mechanical Properties of Concrete Incorporating High Volume Palm Oil Fuel Ash

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.

Palm oil fuel ash (POFA) is solid waste from palm oil industries discarded after burning of shell, fiber, kernel and empty fruit bunches to heat boiler and generate electricity. A standard porcelain consisting of clay, feldspar and quartz is produced by sintering at temperature between 1300 °C to 1400 °C for toughness and translucency. This research developed a prediction model for optimum physical and mechanical properties of porcelain by addition of Fe2O3 at 5 wt.%. Quartz was replaced with POFA powder at 15 wt.% and Fe2O3 was also added at 5 wt.% of POFA mixed with others porcelain composition. Then the powder was dry pressed into pellet at 91 MPa and the samples were sintered at 1150 °C. The bulk density, compressive strength and Vickers microhardness were found to increase by addition of Fe2O3 at 5 wt.%. Prediction model was developed and from the predicted values it is revealed that, the model is efficient and good for the purpose of this research.

This paper presents the utilization of palm oil fuel ash and oil palm kernel shell as cement and sand replacement, respectively in the production of palm oil fuel ash based mortar mixes as part of new and innovative materials in the construction industry. The study includes basic properties such as water absorption, density, compressive strength, and microstructure test with regards to variations in the mix design process. In order to get better performance in terms of strength development, the ash used was subjected to heat treatment and grounded to the size of less than 2 µm. High volume of 80% palm oil fuel ash was used as cement replacement, while 25%, 50%, 75%, and 100% of oil palm kernel shell was used as sand replacement. The results indicated that the density of the mortar decreases with increasing volume of oil palm kernel ash as sand replacement. Three different types of mortar were produced with different percentages of oil palm kernel shell, which was high strength, medium strength, and low strength lightweight mortars.

Nano Size

Palm oil fuel ash is a waste material that can be used as partial cement replacement. However, its reactivity as pozzolanic material depends on the size of the particle. This paper presents the effects of nano size palm oil fuel ash on the long term characteristics of mortar. The study covers basic properties of mortar including the morphology, porosity, compressive strength and microstructural with regards to the variations in the mix design of the mortar. The palm oil fuel ash used has gone through heat treatment and was ground to a nano size with the percentage replacement of cement used was 60%, 80% and 100%. The different types of mortar samples were cast in a 70x70x70mm cube for compressive strength test. All casting and testing of the samples were conducted in the laboratory at ambient temperature. The results show that the use of 80% nano size palm oil fuel ash has produced higher compressive strength at the age of 28 days by 32% compared to the control mortar. Grinding the palm oil fuel ash to a nano size particle has improved the reactivity of the ash and because of it is a waste material it reduces the cost of the mortar. The experimental result also show that the compressive strength of the 80% nano size palm oil fuel ash mortar at 365 days was 25% higher than its strength at 28 days. In addition, the porosity of the 80% nano palm oil fuel ash mortar was reduced by 51% at the age of 1 year. The overall results have revealed that the use of high volume nano palm oil fuel ash can enhances the mortar properties and due to the high percentage of replacement it can contribute to a more sustainable construction.
