Project description
Cement is the most widely manufactured material with large carbon footprint (5-8%). A class of cements based on hydrated magnesium carbonates (HMC) can be carbon net-negative, leading to large scale carbon capture and utilization (CCU) if implemented at scale. Current limitations include poor long-term durability, which may be improved using ligands such as acetate. However more information on the function of acetate is needed. To that end, CCC project will shed light on the fundamental workings of the acetate ligands when used in the HMC cements. Methods include laboratory investigation using nuclear magnetic resonance imaging and synchrotron-enabled methods, accompanied by a variety of computer modelling tools in order to paint a clear picture of the nano-scale function of the acetate ligands in HMC cements. The work will be done at the Fibre and Particle Engineering research unit at the University of Oulu, and the results will bring us closer to enabling carbon capturing concrete.
