Abstract

This study investigates the influence of the incorporation of micronized Polyethylene terephthalate (PET) residues on the physical and mechanical properties of mortars. First, the materials used were evaluated through physical and chemical tests, and then the study of the dosage and molding of the specimens in the dimensions of 5 cm x 10 cm was carried out. The physical and mechanical properties of the mortars were evaluated through the test’s absorption, void index, specific mass, resistance to simple compression, and modulus of elasticity. Incorporating PET to the mortar resulted in an increase in absorption and void index and a decrease in specific mass and compressive strength at the two levels analyzed. Incorporating this material is viable, as the values obtained are within the standardized norms and the use of this residue in civil construction products helps reduce the environmental impact caused by inadequate disposal.
