Carbonation of Mortar with Mineral Admixtures and Relation with Physical Properties

The contribution of three mineral admixtures to the natural carbonation process of mortars was evaluated and related with the porosity, permeability and compressive strength. Twenty formulations were prepared using portland cement, blast furnace slag cement and various proportioning of mineral admixtures introduced as cement volume substitution. The results show that even if globally the carbonation depth is higher for higher porosity, higher permeability and lower compressive strength, the nature of cement and mineral admixture and their proportioning have a very significant influence making it difficult for predicting carbonation depth of mortars with moderate or high rate of admixture from their principal physical and mechanical properties.
