ASH-CEM | a concrete road to circular economy

In the ASH-CEM project (2016-2019) new cement based and carbonation based binders have been developed making use of treated incineration ash from MSWI (Municipal Solid Waste Incinerators) plants, in order to give them a useful destination and avoid landfilling.
The project demonstrated, using the equivalent concrete performance concept, that these novel binders can be used in prefabricated and ready mix concrete for reinforced concrete structural applications when cement based, and unreinforced press manufactured pavement (or similar) products when cement or carbonation based. The project partnership successfully demonstrated:

  • That treated and grinded incineration ash can be used in the raw meal for clinker production (lab scale demonstration)
  • That treated and grinded incineration ash can be used for high end cement replacement in concrete mix design; amongst other this involved the mix design of a high strength concrete for prefabrication and a dry pack concrete for pavers (lab and semi-industrial scale demonstration).
  • That the treated fine incineration ash can be used for dry pack carbonation based press concrete products, such as stones and pavers (lab and semi-industrial scale demonstration).

Watch the ASH-CEM video or the presentations with main project results to learn more. Or contact one of the partners for further inquiries.

The ASH-CEM paver demonstration zone is publicly accessible at the front of Building 60 (same address).

The project is situated in the SIM program MaReS, “Materials from Solid and Liquid Industrial Process Residues”, which amongst other demonstrates the use of industrial mineral residues for building products.
The project is funded by the industry partners (CRH, Indaver, Orbix) and SIM (Strategic Initiative Materials) – VLAIO (Flanders Innovation & Entrepreneurship) – ICON project 150075/76.
