A Study of Rubber as A Construction Material

Concrete is one of the most widely used construction materials. Cement, sand and aggregate, which are the most important constituents used in concrete production, are then vital materials needed for the construction industry. This inevitably led to a continuous and increasing demand of natural materials used for their production. The need for the utilization of the natural resources emerges a growing concern for protecting the environment and a need to preserve natural resources (such as aggregate) by using alternative materials which are recycled or waste materials. Disposal of rubber has before a major environmental issue. Every year millions of tones of rubber discharge and it cause a serious threat to ecology. Most of the rubber waste discharge to landfill or garbage without any treatment. The increasing annual production of rubber is one of the major sources of environmental pollution. This study focuses on the effective utilization of these wastes in cement concrete which leads to an overall sustainable development in the field of concrete. The specimens were cast with percentage replacements of the fine aggregate by 5, 10, 15, 20 and 25% of rubber as coarse aggregate. The experiments were carried out to determine Compressive strength of waste tyre crumb rubber concrete cubes on 7 and 28 days and The results of using waste tyre rubber aggregates in concrete as compared to normal concrete are analysed.
