Chloride Binding of Cementitious Materials Exposed to Sodium

In this work, chloride-binding isotherms are obtained by testing chloride solutions using a calibrated X-ray fluorescence (XRF) device and were evaluated by comparison with titration. Testing was performed on a cement paste with a water-cement ratio of 0.42, exposed to sodium chloride salt solutions ranging from 0 to 5 mol/L at 23°C.
