Zero-CO2 cemeNt ThRough cArBonation of cAlcium Silicates and aluminateS
We live in a world of concrete. According to the Global Cement and Concrete Association (GCCA) cement is consumed at a rate of ~150 tonnes each second, and it accounts for approximately 8% of all CO2 emissions and 7% of industry energy use. In order to mitigate the negative environmental impacts of concrete, Carbon Capture and Utilization (CCU) is the best available strategy: the GCCA estimates that CCU technologies will represent up to 42% of the CO2 reductions necessary to reach the net zero industrial objective in 2050. The CONTRABASS MSCA-DN will act in this framework, in the pathway towards the zero-CO2 cement and concrete production, building a high-quality doctorate network (DN) to investigate the fundamental physico-chemical processes governing the Carbonation of the clinker phases and the cement paste, as well as the subsequent formation of Calcium Carbonate Cements (CCCs).
