Abstract
The amount of construction waste has been dramatically increased in the last decade, and social and environmental concerns on the recycling of the waste have consequently been increased. Waste concrete is one of the crucial among the construction wastes. Recent technology has also improved the recycling process. In this modern industrialized world, recycling construction material plays an important role to preserve the natural resources. Recycled aggregates can be used for cost reduction of the constructional project. In this research work concrete waste from demolished structure has been collected and recycled coarse aggregate (RCA) of different percentage is used for preparing fresh concrete. This study aims to evaluate physical properties of concrete having different proportion of RCA. Mechanical properties such as compressive strength and split tensile strength was determined for various replacement percentages of recycled aggregates. The results obtained are compared with conventional concrete of the same grade.
