Description
Summary:The massive amount of plastic production inevitably leads to huge levels of pollution and, consequently, is threatening the environment and people’s safety. To reduce plastic pollution, research on new ways of reutilization of plastic waste is an open issue nowadays. The main purpose of this work is to evaluate the feasibility of the incorporation of ground polyethylene terephthalate (PET) waste in mortars by comparing the values obtained of mechanical resistance (after 28 days), capillarity water absorption coefficients and thermal conductivity coefficients in an experimental program with the standard values. Mortars prototypes produced at ratios of 1:4 and 1:3 in weight, with partial replacement of the aggregate by PET residuals in different percentages (0, 5 and 10%) were considered. The obtained results show a decrease in mechanical resistance of mortars which was inversely proportional to the use of PET residues in the mixture. An increase in resistance of water absorption by capillary action and a decrease in thermal conductivity was also identified. These results indicate that the replacement of natural aggregates by PET residues in mortars is an interesting option to be considered for the production of a new and environmentally friendly material.
