| description | Waste rubber tires are considered to have substantial environmental and economic impacts, and they are non-biodegradable. This study aims to get rid of waste tires as much as possible and study their benefits and effects on concrete using (chips and crumbs) as an aggregate substitution to fine and coarse aggregates together in making concrete (CRC) and at different percentages of (5, 10, 15, 20, and 25) % by volume. This use can reduce the risk and effect of waste tires. The tests reported a reduction in workability, compressive, and flexural values with the increase in the substitution rate of rubber. Still, other properties such as density and thermal conductivity improved. The registered highest decrease was 2013 kg/cm³ to density and 0.56 (W/m.k) to thermal conductivity with replacement of 50% from waste rubber tiers as an aggregate. The workability registered the highest decrease of 35 mm, compressive strength was 18.5 MPa, and flexural was 3.35 MPa. However, the failure of the (CRC) samples test was not as brittle and abrupt as in the control sample (NSC) in the flexural test. |
