Abstract  

The present research is concerning the characterization of FDR (fuel derived from residues) fly ash and mixtures with lime/brick hydraulic binder by DTA/TG/DTG thermo-analysis, X-ray diffractometry and chemical analysis. The use of hydraulic binder obtained from building brick rejects, which is less expensive than the usual solidifiers such as cementitious binder and silicates, allows us to reutilize, in the meantime, this wreckage material, to the advantage of environmental sustainability. Fly ash samples investigated in the present study were separated in a thermo-incineration plant. Mineralogical DTA/TG/DTG and XRD investigations reveal the presence of different phases as well as chemical analysis shows a moderate concentration of heavy metals and high content of chloride and sulphate. Results obtained from leaching tests with water carried out on hardened pastes containing fly ash lead to interesting results, which highlight behaviour to the release of contaminants. The whole of the results obtained in the present study make it possible to regard the objective of disposing such hardened materials in inert waste landfill sites as achievable.
