Abstract:
The following article aims at analyzing the moisture absorption of polyethylene terephthalate (PET) based composite with geopolymer particles of steel slag. The samples were duly produced in the laboratory, from the slag and PET grinding process, to the geopolymer creation, to the manufacture of the samples with proportions of 0%, 20%, 40% and 60% of geopolymer in the polymer matrix. With the fabrication of the test specimens, the moisture absorption test was performed according to ASTM D570. Changes in porosity, brittleness and other physical characteristics were recorded and analyzed. Through the results, it was verified that the composites with concentrations of 20% and 40% of geopolymers did not obtain great absorptions and greater problems in the processing, encouraging the continuation of the study in search of possible future applications. On the other hand, the composites with concentrations of 60% of geopolymers had a higher absorption having brittle appearance, large amounts of pores and fragility, which made processing difficult. As a complement, having more than just a scientific character, the article serves the purpose of reusing materials commonly discarded in the environment and reusing them in a useful way, and thus following the purpose of sustainability.
