Effects of Recycled Waste Tire Rubber as Coarse Aggregate on the Performance of Concrete

This paper is the second in the series of publishing papers in our research of sound absorption behavior of rubberized concrete. There are very serious problems with the disposal of waste tires in India and worldwide. Because of environmental problem associated with the disposal of waste automobile tires so we need to find an environment-friendly solution. Then this study explores the possibility of reusing tire waste in concrete engineering applications through enhancing the properties of concrete mix as partial replacement with coarse aggregate to produce ideal concrete mix. In this study, percentage replacement of tire waste with natural aggregate in the concrete mix by weight is 0%, 10%, 20%, and 30% respectively. Chipped type generally square in shape and max 20mm in size are used as coarse aggregate. Tests were conducted to determine slump performance, flexural strength, density calculation, water absorption for control and rubberized concrete mix of M25.
