Mineral Carbonation of CO2 with Steel Slags and Waste Concrete

Jun 24, 2015  In fact, construction and demolition waste concrete have the potential to absorb CO2. Naturally, concrete is carbonated by atmospheric CO2. It is due to the presence of reactive elements, essentially calcium. It is s a slow and continual process beginning from the outer surface of the concrete.

Mineral Carbonation of CO2 with Steel Slags and Waste Concrete

Jun 24, 2015  In this project, the main objective is to develop economical mineral carbonation process. In that way, we choose to work at mild conditions without using chemical products, in order to limit energy and chemical consumption. Valorization of products is considered. Waste concrete and steel slags are used as raw material.
