Accelerated Carbonation of Recycled Concrete Aggregates and Model Materials
The accelerated carbonation of recycled concrete aggregates (RCA) has been suggested to improve their properties. Several physical and mechanical phenomena occur during the carbonation of adhered cement mortar, but the relationship between bound CO2 content and the variation of RCA properties is not clear. In this study RCA and model materials (spheres) have been exposed to carbonation, and then characterized at different times to monitor the evolution of their macroscopic properties (porosity and absorption kinetics) as a function of their carbonation degree. A decrease in porosity and saturation rate was actually observed for models materials whereas the initial natural carbonation of industrial RCA limited the storage of CO2 and consequently the evolution of their properties.
