ABSTRACT
The volume of solid waste produced is increasing disorderly and harmful to nature, since they are not given him proper purposes. One of the solid waste that is more worrying environmentalists, society and government are the scrap tires, which have materials in its composition that take hundreds of years to decay. Thus, this study aims to demonstrate the feasibility of using rubber waste tire granulates in the manufacture of common concrete bricks, becoming an alternative destination for tires discarded in the environment. For this purpose, reference bricks (no residue) and 5%, 10% and 20% additions of crumb rubber were produced in replacement of the small aggregate, comparing them by simple compression tests and water absorption in the blocks. In addition, the bricks produced were compared the Ceramic massive blocks used in the region of Catalão, Goiás. There was also the chemical characterization and particle size of the materials used to compose the ecological bricks. In view of the results it is possible to conclude that the blocks with addition of the rubber waste tire presented lower density and own weight, besides having a higher rate of absorption. Regarding the compressive strength, it was observed that there was a decrease of approximately 76% with the addition of rubber, and there was no significant change up to 20% of rubber. Even with these characteristics, the bricks have met the requirements of the standards, which allows their indication for masonry.
