Abstract: A large volume of waste is generated in urban areas. Waste treatment techniques are being adopted in developed countries including recycling of wastes (such as paper, plastic, metals, etc.), composting organic waste and incineration of the remaining fraction. Ash generated as a result of incineration processes presently goes mainly into landfill, increasing both land use and resource wastage. Municipal solid waste incineration (MSWI) fly ash could
alternatively be used as a supplementary cementitious material (SCM) in cement. The major hurdle that currently prevents its use are the expansion of concrete due to elemental aluminium (Al) and also its non-negligible chloride, sulphate, and heavy metal content. Washing with water is the simplest and most effective technique to remove chloride. To prevent Al expansion washing with water and alkali, or washing with a moderate heat treatment were effective. In this research, MSWI fly ash generated in a fluidized bed
incinerator was tested in combination with Portland cement. This paper discusses the conducted experiments with varying parameters and the obtained test results in brief.
