Abstract

Carbonation, reactions between cementitious materials and atmospheric carbon dioxide, is one of the most important mechanisms that determine the longevity of cementitious materials. Despite the recent advances in revealing the carbonation mechanism of cement and concrete materials, the understanding of carbonation mechanisms in low-carbon cementitious materials, particularly low-clinker blended cement (clinker replacement > 60%) and alkali-activated materials, is still limited. This study compares the carbonation performances of a low-clinker blended slag cement and an alkali-activated slag cement via thermodynamic modelling. Phase assemblages of two different types of cementitious materials under accelerated carbonation conditions were predicted by thermodynamic models using the latest CEMDATA18 database. Validation of the developed models were conducted by comparing the predicted results with the experimentally characterised mineralogy from the literature. After validation, the carbonation performances of high-GGBFS blended cement and alkali-activated slag cements are critically compared.
