Replacement of Natural Aggregate by Glass Waste in Granilite Concrete
| Resumo: | The study of polished concrete floors is relevant when related to technical and durability requirements, since its use is very common in places with large extensions. In this exploratory work, it was proposed the comparison between the granolith floor and the floor produced with glass waste to replace the natural aggregate in order to verify the performance of the specimens, in addition to seeking a purpose for the glass, which is barely reused by society. Analyzes were carried out: visual of the specimens; strength to hard body impact; the tensile strength in bending; compressive strength; and hard body impact strength test. Visual analysis identified more intense shine and larger amounts of holes on the surface of the specimens in which the glass was used. In the hard body impact resistance test, the specimens produced with the glass presented superior results when compared to the reference specimens. In the flexural tensile strength test, the specimens produced with the glass (4.3 MPa) presented lower results than the reference specimens (8.0 MPa); nevertheless, both specimens showed satisfactory results. In the compressive strength test, the results obtained in both specimens (13.8 MPa and 18.4 MPa, respectively) were below the minimum required for industrial floors (20 MPa). The hard body impact strength test demonstrated the opposite: the specimens produced with the glass presented higher value (30 cm) than the specimens made with the granite (26 cm).
