description |
In general, with the production of palm oil to cater for the demand of the industry, the
palm oil factory itself generates an amount of waste from its production which
considered as waste solids. Usage of palm oil fuel ash (POFA) is uncontrollable and
minimal which contribute to solid waste in landfills that caused environmental problem.
HoWever, the growing problem of waste materials can be reduced if new recycling
methods can be found for the wastage of palm oil. It has been shown that addition of
pozzolan admixtures such as palm oil fuel ash and fly ash with suitable volume level
can improve the strength and permeability of concrete. It was also found that using such
waste materials result in positive effects on properties of Portland cement mortar and
concrete. This paper presents the effects of ultrafine palm oil fuel ash(POFA) towards
mechanical properties of mortar in different replacement level and compared with
control mixture. In order to improve its properties, the POFA was ground until the
average particle size reducedto 5.91 pm. Then, it was used to replace ordinary Portland
cement (OPC) by weights of 0%, 10%, 20% and 30% in order to improve the
mechanical properties and interfacial zone microstructure of mortar. It was found that
mortar containing ultrafine POFA replacement between 10% and 20% can improve the
workability, compressive strength, flexural strength, porosity, water, absorption and
modulus of elasticity. In addition, cement replacement by 20% of ultrafine POFA gave
the highest compressive strength. The results, therefore, suggest that POFA with high
fineness is suitable to use as cement replacement in improving the mechanical
properties and microstructure of mortar. |
