Project long title

CO2-reduced binding agents through thermochemical conversion of mineral wool waste combinations


Project description

In the BitKOIN project, conceptual, experimental and model research activities are conducted in order to develop a substitute material for ground-granulated blast furnace slag (GGBS). First, mineral wool waste and other mineral residues, which are required as additives to achieve the desired chemistry, are sampled representatively. The materials are then characterized chemically, mineralogically and physically and are additionally classified according to waste regulations. By thermochemical conditioning of the mineral wool waste, combined with the other waste materials, the "Huettensand 2.0" (GGBS 2.0) is developed.

Aims of the project

The contents and objectives of BitKOIN are the functional verification of a concept for the production of "Huettensand 2.0" by thermochemical conditioning of mineral wool waste with other residual materials and the development of a binder. This is followed by a survey of the structural engineering approval requirements and an evaluation of the sustainability of the developed binding agent in comparison with the status quo and the impending scenario after the decarbonization of the steel industry.
