Abstract (EN): 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, a comparison between the granolithic floor and the floor produced with glass waste was undertaken in order to verify the performance of the specimens, in addition to seeking a purpose for the glass, which is barely reused by society. The analyses carried out were: visual observation of the specimens, flexural tensile strength, 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 waste was used. In the hard body impact strength test, the specimens produced with the glass waste presented superior results when compared to the reference specimens. In the flexural tensile strength test, the specimens produced with the glass waste presented lower results than the reference specimens, nevertheless both specimens showed satisfactory results. In the compressive strength test, the results obtained in both specimens were below the minimum required for industrial floors. The hard body impact strength test demonstrated the opposite: the specimens produced with the glass waste presented higher value than the specimens made with the granite.
