FUNDAMENTAL MODELING AND EXPERIMENTAL INVESTIGATION OF CONCRETE CARBONATION

The physicochemical processes in concrete carbonation are presented and modeled mathematically. These processes include the diffusion of CO2, in the gas phase of concrete pores, its dissolution in the aqueous film of these pores, the dissolution of solid Ca(OH)2 in the water of the the pores, the diffusion of dissolved Ca(OH)2 in pore water, its ultimate reaction with the dissolved CO2, and the reaction of CO2 with CSH and with the yet unhydrated C3S and C2S. In addition, the parallel processes of production of materials susceptible to carbonation during the hydration and carbonation, are included in the model.
