Chlorine (Cl) and sulfur (S) in cement

AppNote XRF1250: analysis of chlorine (Cl) and sulfur (as SO₃) in cement

Background

Monitoring proper levels of chlorine is especially vital in producing cement. Soluble chlorine, most often CaCl₂, can be added to concretes and cements as an accelerating agent for faster strength development or shorter setting times. However, the presence of chlorine in reinforced concrete can cause corrosion of the steel reinforcing material, possibly causing premature structural damage. Sulfur in cement is often monitored during the addition of gypsum to the mixtures. The sulfur content in part determines drying rates and strength, as well as the ability of the cement to dry under water. For these reasons it is vital to monitor and control both the chlorine and sulfur levels. To meet this analytical need, Rigaku offer a small, simple to use benchtop EDXRF system ideal for use along the production and QC processes in a cement plant.
