Structural Performances of Recycled Aggregates Concrete Foundation Plinths

The recycling of concrete construction and demolition wastes to obtain coarse recycled aggregates for structural concrete production represents an interesting strategy to develop circular economy in the construction sector. It reduces landfill waste and raw material exploitation. In this applied research, the recycled aggregate, obtained from construction and demolition waste, was used in partial replacement of coarse natural aggregate for casting a set of real scale foundation plinths. These structures have been tested under lateral forces applied on the top of precast reinforced concrete columns connected to the plinths. The mechanism and force characterizing the collapse have been determined showing how concrete structures with recycled aggregates have similar performances to the ordinary ones.
