This work aims at the experimental investigation of innovative cementitious materials that in-corporate recycled waste, in order to boost the transition of the building industry towards a sus-tainable path and for the development of a circular economy. More in detail, vitrified beads, which represent the by-products obtained by an innovative industrial plant that produces low-cost energy (steam and electricity), are used as partial aggregate replacement in mortars. Vitri-fied beads are inserted in the mixes in two different forms: “as they are”, i.e. without any pre-treatment, and after grinding, by replacing in both cases 15% of natural aggregates. The per-formance of the developed mortars with the vitrified beads is assessed both on fresh and hard-ened samples, by means of density and consistence measurements, as well as by performing compressive and three-point bending tests. The obtained experimental results show that this by-product could be a promising waste to be recycled into construction cementitious materials.

Abstract
This work aims at the experimental investigation of innovative cementitious materials that in-corporate recycled waste, in order to boost the transition of the building industry towards a sus-tainable path and for the development of a circular economy. More in detail, vitrified beads, which represent the by-products obtained by an innovative industrial plant that produces low-cost energy (steam and electricity), are used as partial aggregate replacement in mortars. Vitri-fied beads are inserted in the mixes in two different forms: “as they are”, i.e. without any pre-treatment, and after grinding, by replacing in both cases 15% of natural aggregates. The per-formance of the developed mortars with the vitrified beads is assessed both on fresh and hard-ened samples, by means of density and consistence measurements, as well as by performing compressive and three-point bending tests. The obtained experimental results show that this by-product could be a promising waste to be recycled into construction cementitious materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
