Investigation On The Potential Application Of Mswi Bottom Ash As Substitute Material In Portland Cement Concrete

Abstract

This study investigates the potential use of Municipal Solid Waste Incineration (MSWI) bottom ash as a substitute material in cement concrete. The physical and chemical properties of MSWI bottom ash were characterized, and its effects on the mechanical and durability properties of concrete were evaluated. This research explores the feasibility of utilizing MSWI bottom ash as a substitute material in cement concrete. This study demonstrates that Municipal Solid Waste Incineration (MSWI) bottom ash can be effectively used as a partial replacement for cement (up to 20%), enhancing the mechanical properties of concrete. The results show promising potential for MSWI bottom ash as a substitute material in cement concrete, offering a sustainable solution for waste management and resource conservation. This study demonstrates that incorporating Municipal Solid Waste Incineration (MSWI) bottom ash as a cement replacement in dry-cast concrete enhances early-age and late-age hydration, improves freeze-thaw performance, and offers environmental and economic benefits.
