摘要
Seeking to contribute to reduce the impact of improper disposal of tires on the environment, this article proposes the use of tire rubber as fine aggregate in the production of concrete. The specimens of dimensions 160 mm x 40 mm x 40 mm were made in the 3:2:1 trace and rubber was used to replace sand as fine aggregate, in the proportions of 5%, 10% and 15% by weight. Compression and flexion tests were performed at 7, 14 and 28 days of cure using a Kratos press, with a maximum cell of 10 tf (98.07 kN), and with a displacement speed of 5.0 mm/min. The results suggest that crushed rubber has restricted use as a substitute for fine aggregate concrete. At 7 days of curing the best result of mechanical compressive strength was 19 N/mm(2) and for flexural strength was 5.9 N/mm(2) both for 5% rubber replacing fine aggregate.
