Sulphide Sulphur Content of Concrete Aggregates

The deterioration of concrete in buildings across Canada, due to the chemical reaction of iron sulphides, is a significant issue. CSA Group supported a major research undertaking to further explore this issue in an effort to produce more information that can be used to inform the basis of the future edition of CSA A23.1-14/A23.2-14 – Concrete materials and methods of concrete construction / Test methods and standard practices for concrete. This executive summary outlines our methodology and details our observations to date.
