Summary

This report gives guidance on the assessment of brownfield sites that may contain ferrous slags, so that any expansive potential may be taken into account when development of sites is planned or when the buildings or structures are designed.

The report covers the general investigation of potentially contaminated sites intended for development. It describes the origin, occurrence and characteristics of blastfurnance and steel slags that may be expansive, and gives guidance on the identification of slags and on testing for expansive potential. The assessment and risk management of ferrous slags in relation to built development is also covered.
