Abstract—Concrete is one of the most widely used construction materials in the world. Cement 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. Parallel to 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. In this research, a study was carried out on the use of recycled rubber tires as a partial replacement for fine aggregates in concrete construction using locally available waste tires. The work was carried out by conducting tests on the raw materials to determine their properties and suitability for the experiment. Concrete mix designs are prepared using IS method for M20 grade of concrete. The specimens were cast with percentage replacements of the fine aggregate by 5, 10, 15 and 20% of rubber as fine aggregate. Moreover, control mixes with no replacement of the fine aggregate were cast to make a comparative analysis. The prepared samples consist of concrete cubes, cylinders and beams. Laboratory tests were carried out on the prepared concrete specimens. The lists of tests conducted are slump, compressive strength, split tensile strength and flexural strength tests. The data collection was mainly based on the tests conducted on the prepared specimens in the laboratory.
