Geotechnical Properties of Iron and Steel Making Slag Aggregates Stabilised with Binders for Pavement Base/Subbase Applications

In this research, the geotechnical and environmental characteristics of iron and steel making slag aggregates have been evaluated to be used as a construction material in unbound, cement-stabilised as well as geopolymer-stabilised pavement applications. Traditional stabilisation methods such as cement stabilisation are not entirely sustainable options, hence liquid alkaline activator along with low carbon pozzolanic binders, namely fly ash and slag, were used for geopolymerisation study. The usage of slag aggregates as construction material in roadwork applications would bring about a practical end-of-life alternative for their sustainable reuse and possibly divert large amount of these waste materials from landfills.
