Impact of slag on carbonation rate of concrete based on calcium aluminate cement [PDF]

open access: yesMATEC Web of Conferences, 2022
Throughout their service life, concrete structures are exposed to various environmental conditions that affect their durability. The cementitious matrix inevitably comes into contact with air, which leads to a progressive carbonation reaction.
