The concept
This Priority Programme is pursuing scientific breakthroughs on the main components employed in concrete, viz. alternative binders, renewable aggregates, and concrete as a carbon sink to achieve a CO2 neutral concrete. Novel research pathways towards a climate neutral concrete will be explored and evaluated. Multidisciplinary research, covering cement chemistry, concrete technology, civil and materials engineering as well as related scientific areas such as physical chemistry, reaction thermodynamics and kinetics, and physics of materials, but also reusability and adaptability of resources and production procedures will be considered. From this, the following three objectives will be emphasized for achieving a net-zero concrete based on a cumulative CO2 reduction that are representing the SPP’s research directions:
- Experimental and numerical research on alternative binders and novel clinker raw materials in terms of composition and reactivity of individual phases and CO2 interactions;
- Development of waste-based and/or renewable aggregate systems that have the potential to absorb CO2, are fully recyclable and/or reusable in an end-of-life scenario;
- Development of advanced concrete carbonation strategies to maximize CO2 uptake in concrete production as well as during and after service life.
