 SummaryThe project « Tefracem » (Tefra = fly ash in Greek) has been introduced at the Brussels Region with two Applied Sciences Departments of the Free University of Brussels, ULB (BATir, Professor S. Staquet and CREA-SURF, Professor M. Degrez) within the framework of the Impulse Programme – Environment call 2008. The aim of this research is to valorise the residues of the Neder-Over-Hembeek incinerator in construction materials; more precisely, the project foresees to treat the fly ashes and the residues obtained from the purification of the incinerator outlet gasses and add these materials to the cement as a hydraulic binder (mineral addition of type II) or, if necessary, to use them as an inert filler as sand in concrete. This research started in 2009. The CRIC-OCCN will deal essentially with the following tests: - the characterization of MSWI and the study of the reproducibility of their elementary chemical properties during their production; - the study of their eventual incorporation in cements; − the leaching of MSWI before and after treatment; − the leaching on the final products (concrete); − the durability of these new concretes. |
