Abstract: The disposal of personal protective equipment (PPE) is a main concern of researchers. In recent years, the COVID-19 pandemic made this issue worse, so the production and use of large quantities of disposable gloves in recent years and the lack of a suitable solution for the disposal of these recycled materials are some of the consequences of this pandemic. To address this issue, the present study performed a comprehensive experimental program to determine the possibility of using recycled latex and vinyl gloves as recycled fibers within extrusion-based 3D printing concrete. Moreover, a graphene oxide (GO) nanomaterial was also used to compensate for some undesired properties of mixtures. Flow table, buildability, and mechanical tests were performed in this study. Results show that the synergic effect of recycled fibers and GO significantly improved the 3D printing characteristics of mortar. Although very promising results were obtained in this study, findings show that using a high content of recycled fibers reduces the concrete compressive strength. However, the addition of GO significantly compensates for this reduction.
