Abstract:

APC (air pollution control) fly ash, generated in incineration process of municipal solid waste, is regarded as a hazardous waste because of enrichment of heavy metals. In this work, stabilization of the ash with cement was studied. In addition, XRD analysis of the cement stabilized body was performed as a function of conservation time period. It was It was found that the hydration products cement fly ash and other particles together, which rises with increase of the cement / ash ratio and duration of conservation. Major mineralogical compositions CaCO₃, Ca (0H)₂ and C-H-S hydration products. Content of Ca (0H)₂ and C-H-S rises with increase of conservation period and cement / ash ratio.
