Abstract:
In this presentation, we demonstrate an effective way to enhance the CO2 capture and minerali-zation capacity of concrete by controlling the carbonation kinetics within the cementitious matrix using 1D and 2D carbon-based nanomaterials. When added in a cementitious system, carbon-based nanomaterials provide a unique platform for enhancing the interactions between CO2 and C-S-H due to the ultra-high surface area, essential for surface chemistry. Compared to the CNTs, graphene engineered concrete exhibits a 50% higher CO2 sequestration capacity, due to the 2x higher specific surface area of the 2D GNPs.
