Seismic Behavior of RC Frame Structures Made with EAF Slag Aggregates

Recycled aggregates are increasingly being used in the construction industry. Among others, Electric Arc Furnace (EAF) slag aggregates have been proven to be promising both in terms of sustainability and material properties. However, EAF concrete is also characterized by a higher specific weight with respect to natural aggregates (NA) ones and while good results have been obtained for elements subjected to static loads the behavior of EAF RC structures under dynamic loads is yet to be investigated. Therefore, the present paper aims to investigate the seismic response of reinforced concrete (RC) frames made with EAF in comparison to the same frames made with NA concrete.
