Multi-Laboratory Study of Proposed New Test for Determination of 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 gain 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 report outlines our findings.
