Properties of different types of concrete containing waste tires rubber- A review

Abstract

According to Rubber Manufacturer's Association, about 270 million waste tires are produced in United States each year. Also about 300 million scrap tires are stockpiled at the United States. Significant development in transportation and an enormous increment in the quantity of vehicles create various issues, for example, environmental contamination. Many research studies utilized scrap tires rubber in different types of concrete mixes such as normal concrete and self-compacting concrete to produce rubberized concrete and self-compacting rubberized concrete. This review paper presents important results and conclusions that obtained from previous studies which used waste tires rubber as aggregates (fine and coarse aggregates). The results showed that the mechanical properties (compressive strength, splitting tensile strength, and flexural strength) decreased by adding rubber particles. Also the fresh properties negatively affected as rubber contain was increased but stay in the acceptable limits. The failure mode of concrete change from brittle to ductile by incorporating scrap tires rubber in concrete.
