Abstract: Ingress of chloride ions through concrete is known to be the most important durability concern. Development of new cementitious materials is rapidly evolving, which is due to environmental and economic motivations. One of the promising blended cements is composed of ternary mixture of Portland cement with calcined clay and limestone (known as LC3). Calcined clay in LC3 Systems are kaolinitic, which are abundant on the earth’s crust with variable kaolinite content. While most of the past research has focused on high purity clays, the durability performance of LC3 systems made using intermediate grade clays are evaluated in this study. The rate of chloride diffusion, as well as the interaction of chloride ions with the solid phases are quantified. The interactions are assessed using XRD-Rietveld analysis and measurement of chloride binding isotherms.
