| Summary: | Palm oil fuel ash (POFA) has been known to possess a pozzolanic property. The
abundance of POFA as an agricultural waste makes it a promising candidate for it to
be used as a supplementary cementations material in palm oil producing countries.
Trlls paper presents structural analysis and surface morphology of a treated Palm oil
fuel ash (POFA). The untreated POFA was grounded for 1.5hours in a ball mill to
reduce the particle size and to improve reactivity. It was then heated at a temperature
of 600°C 1.5hours in an electric furnace. X-ray fluorescence (XRF), X-ray diffkaction
(XRD) and scanning electron microscopy (SEM) were used to observe the surface
and internal structure of the POFA. The results among other things revealed that the
POFA consist of mainly silica (SOz), with crystalline structure, microscopic
examination showed that the POFA has a porous cellular structure and consists of
irregular-shaped particles. This study implies that POFA is good candidate for various
applications by ceramic industries. |
