Reduction of carbon dioxide emissions by replacing Portland cement with carbonation-activated slag

Funding : The Fonds de recherche Nature et technologies [Nature and Technology Research Fund] of the Government of Quebec (Professor Shao, McGill University)

Period : 2018—ongoing

Description : This research project aims at reducing the environmental footprint of cement and concrete product manufacturing through a circular economy strategy involving the steel industry. The mitigation option relies on the innovative use of steel slag as a cementing material which upon carbonation activation and wood chip fillers can produce cement-free and carbon-negative construction blocks. The modelling of the entire supply chain with NATEM allows for the study of optimal market conditions for these innovative construction products and the extent to which they can contribute to the mitigation of greenhouse gas emissions in Quebec.
