Capture and storage of Co2 by carbonation of clinker and concrete with reduced cement content

The demographic and economic growth of the past few decades has led to additional industrial activity triggering a considerable increase in greenhouse gas emissions, responsible for major climate changes. The European Union has set itself the goal of a net reduction in European emissions of at least 55% by 2030, in order to achieve carbon neutrality by 2050. In this context, the project’s industrial partners (Ipalle, TRBA and  Roosens bétons) have logically identified a convergent interest in using CUSC technology (Capture, Utilisation and Sequestration of CO2) to reduce the carbon footprint of their products via the partial replacement of cement by carbonate phases. It is in this context that they called upon the scientific support of the CTP and the University of Liege’s GeMMe and PEPs laboratories in order to investigate the development of road engineering materials or prefabricated concrete materials enabling the sequestration of industrial CO2.
