dc.description.abstractRecycling of agricultural wastes such as rice husk ash as pozzolan is being increasingly encouraged, particularly in developing countries. In this paper, preliminary investigation on the physical and chemical compositions of rice husk ash using different techniques was carried out. Scanning Electron Microscopy (SEM) images of the rice husk ash showed residual pores to be distributed within the ash sample, indicating that the silica is a highly porous material with a large internal surface area. Samples burnt at 4000C for 6 hours and 6000C for 4 hours for ‘Bukus’ and ‘Soro/ Olomo nla’ show aggregates with clearly defined layers of loose flakes compared to ‘Faro 58’. The Energy dispersive x-ray spectroscopy (EDX) analysis of rice husk ash performed to determine percentages of silica present in the samples were graphically represented. Nine elements (Al, Si, K, Ca, Br, Fe, Mg, Na, Mn) and their corresponding oxides (Al2O3, SiO2, K2O, CaO, Br, Fe2O3, MgO, Na2O, MnO) were detected with varying concentrations. The three varieties, on the average possess good silica content of over 50% considering the two varied temperature and time. Therefore, the chemical analysis results show that burning at combustion temperature of 6000C for 4hrs, gives optimal result than at 4000C for 6hrs because all the samples show high Silica content (Faro 58; 61.9, Bukus; 62.6 and Soro/Olomo nla; 59.5)en_US
