Study on Physical and Chemical Properties of Fly Ash from Different Area in Malaysia

Abstract

Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash mostly consists of silicon dioxide (SiO2), aluminium oxide (Al2O3) and iron oxide (Fe2O3). The chemical compositions of the sample have been examined according to ASTM C618. Different sources of fly ash may result in different chemical composition. The fly ash is mainly an amorphous material with the presents of crystalline phase of quartz and mullite. Fly ash consists of mostly glassy, hollow and spherical particles.

Keywords; Fly Ash, SEM, XRD, XRF
