Utilization of rice husk ash (RHA) into ceramic brick


Aneis Maasyirah Binti Hamzah (2019) Utilization of rice husk ash (RHA) into ceramic brick. Final Year Project thesis, Universiti Malaysia Kelantan. (Submitted)


Silica from rice husk ash (RHA) and clay were progressively involved in the production of whiteware material especially ceramic. The increases in the amount of paddy residue generated from time to time has lead to the introduction of rice husk ash uses in the manufacturing of ceramicbrick as thealternativeapproach towards sustainableindustry. The influence of the addition of RHA weight percentage as the silica precursor for the body formulation (0 wt. %, 20 wt. % and 40 wt. %) and also range in firing temperatures (900℃, 950℃ and 1000℃) were used as the parameter to study their effect on the firing shrinkage, volumetric shrinkage, water absorption, apparent porosity and bulk density. It has been found that the replacement of quartz by RHAreduced the water absorption as well as the apparent porosity especially at maturing temperature of 950℃ to 1000℃ with 40 wt. % of RHA. The utilization of RHA as the ceramic brick give the value of percentage water absorption at 0.71%, apparent porosity at 0.86%, firing shrinkage at 8% to 10% and volumetric shrinkage at 0.8%.The finding would be helpful to improve the properties of ceramics as well as reducing the energy consumption during firing process. Apart from developing the green technology in production of ceramic, it also helps in decrease the amount of waste generated from the agriculturalwaste.
