Sustainable Utilization Of Mswi Bottom Ash As Road Construction Materials, Part Ii: Chemical And Environmental Characterization
Incineration of municipal solid waste (MSW) is a common technology that converts solid waste into energy. In European and Asian countries, municipal solid waste incineration (MSWI) ash has been beneficially utilized by separating the bottom ash from fly ash and using them as road construction materials. Generally, MSWI bottom ash, classified as nonhazardous materials, is used to replace either cement or fine aggregate in asphalt and concrete mixtures. In this study, chemical and microstructural analyses of MSWI bottom ash (\u27as received\u27 samples) produced from a Refuse Derived Fuel (RDF) plant in Florida were conducted. The characterization method included energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) methods. Subsequently, leaching behaviors of bottom ash-mixed asphalt and concrete mixtures (for milled asphalt and crushed concrete applications) were investigated. The Synthetic Precipitation Leaching Procedure (SPLP) testing method was used for the leaching investigation
Effect Of Chemical Treatment Of Mswi Bottom Ash For Its Use In Concrete
In this paper, municipal solid waste incineration (MSWI) bottom ash was characterised before and after chemica treatment and the effect of ash addition on the performance of concrete as a partial replacement of fine aggregate was evaluated. The chemical treatment aimed to eliminate the side effect of MSWI ash - the creation of a network of bubbles - which can eventually lead to a significant reduction of the overall performance of concrete Petrographic examinations, energy dispersive X-ray spectroscopy and X-ray diffraction, were carried out to chemically characterise the MSWI bottom ash. The mechanical performance of the ash-combined concrete was evaluated by measuring its compressive strength. Analysis of the measured data demonstrates that the chemica treatment successfully transformed metallic aluminium in the ash into a stable form and hence expansion of the concrete due to hydrogen gas evolution was no longer detected in the concrete containing treated ash Consequently, compared with specimens with untreated ash, concrete specimens with treated bottom ash showed improved performance
