Resumo:
Ethylene Polyterephthalate (PET) is a thermoplastic widely used worldwide for
packaging manufacturing. The low cost of production and the consequent
improvement of its manufacturing process has made PET one of the main plastics
of today. For the production of mortars, the addition of polymers improves
rheological properties, generating greater mechanical strength, improving
physical and state properties, and reducing and / or improving the final disposal
of this product on the environment. The main objective of this work is to evaluate
the feasibility of partial replacement of the fine aggregate by Polyethylene
Terephthalate (PET) in the contents of 0, 5% and 10%. Cylindrical samples were
molded in the dimensions of 5cm x 10cm and the absorption by immersion, voids
index, specific mass and the simple compressive strength for the ages of 7.14
and 28 days were determined. The results show that there was an increase in
water absorption, voids index and a reduction in the specific mass of specimens
incorporated with PET when compared to the reference mortar. For the tensile
strength mechanical test there was a reduction in the values of the modified
mortars with PET.
