 Summary
The 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 recently accepted 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 or fine gravel. This research that starts in 2009 will finance three PhD thesis’s of which one will be performed by the CRIC-OCCN. The CRIC-OCCN will deal essentially with the following tests: − − the leaching of fly ashes after treatment;; − − the leaching on the final products (concrete produced with cement containing these fly ashes); − − the durability of these concretes. |
