Abstract
The planet has been facing several environmental problems, most of which come from civil construction waste, which, in addition to being a major polluting source, still requires a large amount of raw materials removed from the environment. In order to minimize these damages, the present work aims to reduce the extraction of sand from river beds and reduce the incorrect disposal of packaging produced with polyethylene terephthalate (PET) through the partial replacement of the fine aggregate by PET in the production of mortars. Prismatic specimens were be produced with curing in 28 days of 25 °C and partial replacement of 10, 20 and 30% of the natural sand by the waste. Tests were performed on consistency, viscosity, density, mechanical strength and capillarity will be performed tests. The results showed that the partial replacement of natural sand by PET is feasible, despite some observed viscosity losses, making this mortar more ecological.
