Chemical Realkalization of Carbonated Concrete: Influence of Cement Composition on Alkalinity Restoration and Portlandite Formation

Chemical Realkalization of Carbonated Concrete: Influence of Cement Composition on Alkalinity Restoration and Portlandite Formation

This study examines the carbonation and realkalization dynamics of various cementitious systems, with a focus on the influence of cement composition on their susceptibility to carbonation and potential for realkalization. Four cement types were evaluated: CEM I, CEM II/A-LL, CEM II/A-V, and CEM II/B...
