USE OF RUBBER WASTE IN CONCRETE TO REDUCE ENVIRONMENTAL POLLUTION- AN OVERVIEW

With on growing industrial development, tonnes of solid waste are generated every year. Managing, disposing and recycling of these waste has turned out to be a great challenge in recent times. Typically, waste generated from industrial and domestic activities is dumped in open spaces. However dumping of solid waste in open spaces is hazardous to environment; therefore researchers have explored new means to effectively manage such waste. Tyre wastes have no exception; it cannot be readily recycled or reused. They are dumped in open grounds around the world. In Pakistan they pose a bigger threat as they are burnt, which results in emission of harmful gases in the atmosphere. Therefore, it is necessary to reuse these rubber wastes to reduce environmental pollution. Rubber wastes can be used in concrete as a partial replacement of aggregates resulting in lightweight concrete. Using rubber wastes in concrete enhances the impact resistance, thermal insulation and sound insulation at affordable strength. This paper reviews the viable use of rubber wastes in concrete industry to address the problem of disposal of such wastes.
