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 particularly crucial among the construction wastes. Recent technology has also improved the recycling process. In this rapid industrialized world, recycling construction material plays an important role to preserve the natural resources. This study aims to evaluate physical properties of concrete using recycled coarse aggregate. In this research concrete waste is from demolished structure (Near Kamla Nehru Park, Bhandarkar Rd, Pune) has been collected and coarse aggregate of different % is used for preparing fresh concrete. The amount of recycled coarse aggregate used in this research is approximately 125 kg. Many researchers state that recycled aggregates are only suitable for non-structural concrete application. This research, however, shows that the recycled aggregates that are obtained from concrete specimen make good quality concrete. The compressive strength of recycled coarse aggregate (RCA) is found to be higher than the compressive strength of normal concrete when used upto a certain %. Recycled aggregate concrete is in close proximity to normal concrete in terms of split tensile strength. The slump of recycled aggregate concrete is more than the normal concrete. At the end it can be said that the RCA upto 50 % can be used for optaining good quality concrete.
