HOW TO REPLACE CONVENTIONAL CONCRETES WITH A MORE EFFICIENT AND CIRCULAR ALTERNATIVE IN THE CONSTRUCTION OF COMMERCIAL AND INDUSTRIAL BUILDINGS?

GreenWin presents GEOSLAGS :

The GEOSLAGS project, supported by an exclusively Walloon consortium, proposes the
creation of an entire new value chain in Wallonia that allows for, to start with, the construction
of commercial and industrial buildings by using a novel geopolymer hybrid that presents
with mechanical or thermal performances able to be adapted to requirements.

This alternative solution to conventional concrete, developed on the basis of a hybrid geopolymer
binder capable of fulfilling the role of cement in the formulation of concrete, and
with a resistance that is similar if not superior to the one afforded by standard concrete,
will incorporate a maximum of stainless-steel slags, which it is currently not possible to
valorise, thus reinforcing the circularity of the industrial sector.

In addition, it will also contribute to reducing, or to completely eliminating, the use of rolled
sand, already in short supply and the exploitation of which gravely harms marine ecosystems,
or of crushed natural sand.

The circular nature of the project and the environmental benefits will be validated and quantified
by a Life Cycle Analysis (LCA).

Les « + » :

Innovative low-carbon Walloon alternative to standard concrete within the context of the construction of prefabricated commercial or industrial buildings.
Valorisation of a fraction of stainless-steel slags accumulating though lack of a valorisation route.
Supply of a material with a density that can be modulated and with thermal insulating properties that can be put to good use to provide a replacement for insulation currently in use by offering an additional attribute of total resistance to fire.
