Resumen
Prefabricated concrete panels for building facades with partial replacement of cement by natural pozzolan, and partial replacement of aggregate by PET (polyethylene terephthalate) flakes. The reinforcement is made from PET plastic waste in the form of filaments for 3D printing. Preferably, the panel uses locally sourced materials, reducing energy consumption in transportation and supporting the local economy. It also utilizes plastic waste, preferably of local origin, promoting a circular economy. In the case of the studied geographical area, the Canary Islands, the carbon footprint is minimized since maritime transport is not required for the import of raw materials and the removal of waste.
