Properties of Concrete with Municipal Solid Waste Incinerator Bottom Ash
The appropriate utilization of Municipal Solid Waste Incineration (MSWI) residues is a worldwide studied topic over the last decades. One of the possibilities is to use MSWI ashes in concrete production, as it is done with coal combustion products. The bottom ash features the most convenient composition for this purpose, and it is available in highest amounts among the MSWI ashes. Untreated bot...
متن کاملUtilisation of two-stage waste incinerator bottom ash as a cement substitute in concrete
Waste incineration still seems to be an essential technology in the concept of integrated waste management. However, the desirable quantity of waste incineration residue needs to be as low as possible. Therefore, related optimization of two-stage waste incineration technology has been performed with the main goal of producing lower amounts of boiler ash, fly ash and flue gas-treatment residue, ...
متن کاملIncinerator Ash - Criteria of Performance
The object of this paper is to throw light on the criteria which apply to the degree of burn-out on a furnace burning mixed household and trade refuse. In particular, the paper concentrates on the ash discharged from the end of the grate since this represents the bulk of the ash produced by the plant. The classical approach to burn-out is to employ "carbon-in-ash" techniques familiar to combust...
متن کاملChloride extraction for quality improvement of municipal solid waste incinerator ash for the concrete industry.
Coal ash from power stations has long been used successfully in the cement industry as binders in several Portland formulations. This is not the case for municipal solid waste (MSW) ash as chloride concentrations, ranging from 10 to 200 g kg(-1) dry weight in the bottom and fly ash, respectively, exceed the maximum allowable concentration in most cement mixtures. To reduce chloride content in M...
متن کاملProduction of glass-ceramic from incinerator fly ash
Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), whic...
