Seismic reliability of RC buildings made with EAF concretes

The development of sustainable concretes is becoming an emerging issue in civil construction sector. The use of recycled aggregates is one way to fulfill sustainability goals in concrete industry, and among others, Electric Arc Furnace (EAF) slag aggregates has been proven to be promising. Past research demonstrated a significant increase of mechanical properties of EAF concretes when compared with ones made with natural aggregates (NA); however, at the same time, their use implies also an increase of self-weight loads. The present study aims therefore to investigate the seismic reliability of reinforced concrete frame buildings made with EAF, and compare it with the same structural configurations built with NA mixes, in order to show how the change in mechanical properties and self-weight can impact the seismic response of the analyzed case-studies.
