Investigate the Properties of Solid Waste Bottom Ash (SBA) and Lime Reinforced in Composite Bricks

Abstract

This research studies on the possibility of producing a more sustainable lightweight brick. Solid waste bottom ash (SBA) and lime found in area of Ratchaburi province of Thailand were mixed into the composite brick for the replacement of fine aggregates and Portland cement contents, respectively. Effects of varied amount of SBA and local lime contents typically (10, 20, 30, 40 and 50% by weight) on mechanical and physical properties of bricks were studied. Results showed that with the replacement cement and fine aggregate of 20% by weight with SBA and local lime, respectively showed the maximum values. Similarly, the thermal conductivity and density and product weight showed the maximum values at the same replacement contents. By conclusion, this application may be an interesting solution in order to improve sustainability and energy efficiency of the low cost house in local area of Thailand.
