Compressive strength and heavy metal leaching of concrete containing medical waste incineration ash

This paper provides the results of the study on solidification/stabilization (S/S) of medical waste incineration bottom ash (MWBA). S/S is a process reducing heavy metals leachability of materials, and so as permitting disposal of them in a sanitary landfill. This process can be also described as a recycling facility because the usability of solidified matrix as a building material according to mechanical characteristics. In this study, S/S process was studied at different ratios of ash/cement mixture (0%, 5%, 10%, 15%, 20%, 25%, 30%, 40% and 50%) and two different curing times (7 days and 28 days).
