Incineration, which is a viable alternative for processing of municipal solid waste (MSW), reduces the volume of the waste destined for landfills. Results from a recent study on physical, chemical, and engineering properties of MSW mixed with top and bottom ash are presented. These results can be used to assess the possibility of using MSW incinerator ash for certain construction purposes and soil stabilization applications. Some of the test results are compared with those of fly ash (coal burning) cement composites for assessment of their potential use. The MSW ash-cement composite was investigated for strength characteristics at various stages of maturity. The independent variables considered were MSW ash content, sand content, and water cementitious ratio. The ash-cement ratio was varied from 10 to 20. Water-cementitious ratios of 0.45 and 0.6 were investigated. The response variables in this study included compressive strength and splitting tensile strength. Strength tests were conducted at 3, 7, and 28 days of maturity. Tests were also performed to determine the maximum density and optimum moisture content of the MSW ash as needed for field applications.
