Chloride binding assessment in C3S systems with calcined clay

Chloride binding is an important factor for chloride transport in cementitious materials, which can fix the chloride on the solid phase and decrease the free chloride content. As an alumina-rich supplementary cementitious material, calcined clay can be applied to improve the binding capacity of the system. While the contribution of calcined clay...

Advanced characterization of chloride binding in OPC and LC³ pastes

The incorporation of supplementary cementitious materials (SCMs) in cement pastes enables both decreasing CO2 emissions and increasing the concrete durability, notably with a better resistance against chloride ingress and thus retarding the chlorideinduced corrosion of steel rebars. Nevertheless, a better understanding of the chloride fixation...
