- Abstract
This paper investigates the possibility of using rubber waste from scrap tires as replacement of coarse aggregate in concrete. Performance of concrete mixtures incorporating 5, 10 and 15% of scrap rubber as volume replacement for coarse aggregate was investigated. Compressive strength, flexural strength, stress-strain behavior, workability, air content, water absorption and unit weight were evaluated using standard procedures. Thermal behavior for concrete was examined using hotbox technique. No remarkable changes in concrete properties up to 5% substitution were occurred. Beyond 5% substitution, concrete properties change appreciably. Compressive strength, flexure strength, workability, stiffness and unit weight of rubberized concrete decreased as rubber content increased. While impact resistance, air content and water absorption of rubberized concrete increased with increase in rubber content. Thermal performance of concrete containing rubber aggregate was improved, and promising results were obtained. Thus, rubberized concrete could be useful in slabs to improve energy efficiency of building unit.
