The current preferred method for reducing the CO2 content of cement is to replace part of the clinker by “low carbon” components with proven binding properties. This research aims to demonstrate the production of substitutes with hydraulic and / or pozzolanic properties based on the thermal treatment of locally available secondary raw materials from the gravel, clay and limestone (dolomite) industry. This mainly concerns industrial by-products and/or wastes from gravel/clay pits and quarries. This research needs to apply various characterisation methods such as chemical, mineralogical and thermal analyses, particle size analysis, electron microscopy, etc. The aim is to assess the potential reactivity of the selected raw materials and to determine the most suitable thermal and physico-chemical treatment processes.
After achieving highly interesting scientific results within a first research project in Luxembourg, Prof. Waldmann enlarged the initiative to the Greater Region and currently leads as PI the INTERREG project CO2REDRES on this subject.
