Valorization of waste concrete through CO2 mineral ...

2017-11-10  The use of CO 2 mineral carbonation represents an attractive approach to recycling waste concrete. In this study, the effect of gas pressure, Liquid/Solid (L/S) ratio (w/w), Gas/Liquid (G/L) ratio (v/v) and reaction time for CO 2 sequestration were investigated. While carbonation of such matrix is already described, this study opens new insights in concrete carbonation.

Mineral Carbonation of CO2 with Steel Slags and Waste

2015-6-24  Concrete represents more than 50% of construction and demolition wastes. (Nisbet, Venta et al. 2012) This considerable quantity should be re-used in the proper way, especially in CO2 sequestration. In fact, construction and demolition waste concrete have the potential to absorb CO2. Naturally, concrete is carbonated by atmospheric CO2.
