Influence of Supplementary Cementitious Materials on Transport Properties of Concrete And Interfacial Transition Zone

Transport properties of concrete directly affect durability. A good comprehension of different transport properties and the role of supplementary cementitious materials (SCMs) will help in improving concrete quality. This article presents a brief review of the role of SCMs in concrete, transport mechanisms and their correlation with durability. The progress of research on transport properties like water penetration, sorption, electrical resistivity, chloride ingress, etc. with the partial replacement of different blenders is reviewed. The article also briefly examines the influence of SCMs on the interfacial transition zone (ITZ) and the link between ITZ and overall transport properties.
