Abstract

Municipal solid waste incinerators (MSWI) produce by products which can be classified as bottom and fly ashes. The bottom ash accounts for 85-90 % of solid product resulting from MSW combustion. The objective of this study was to assess the feasibility of application of municipal solid waste incineration (MSWI) bottom ash as a supplementary cementations material for the preparation of blended cement. The used of bottom ash as a research material is caused by substances contained in cement is almost the same with bottom ash. Bottom ash was found to have some reactivity, but without greatly affecting the hydration process of OPC at 10 % replacement with 10% metakaolin is required to be used in the production of concrete in order to improve strength.
