Carbonation of concrete with mineral additions
Paper i proceeding, 2017

This study investigated how mineral addition, fly ash and slag (GGBS), influences carbonation, and how carbonation affects chloride migration and transport properties in mortar. Accelerated carbonation, Rapid Chloride Migration (RCM), capillary absorption tests (NT Build 368) and compressive strength tests (SS-EN 196-1) were conducted in a comparative study of mortar mixtures with different levels of mineral addition and w/b ratios. Carbonation rate increased and compressive strength was reduced with increased amount of mineral addition. The results also showed an interdependence between different deteriorating processes. Carbonation reduced the porosity, rate of reaching saturation and connectivity of the pore structure.
