Abstract:
In this presentation the CO2 uptake and mineralization potential of OPC Concrete with surface-treated recycled aggregates and nano-TiO2 are demonstrated. Accelerated carbon curing was per-formed to evaluate the synergistic effect between surface-treated recycled concrete aggregates and nano-TiO2 on CO2 sequestration. Thermogravimetric analysis results showed that addition of nano-TiO2 increased the CaCO3 amount formed within the cementitious matrix. The findings indicate a higher CO2 uptake and mineralization capacity of the nanomodified concrete compared to the OPC concrete.
