Recycled aggregate concrete (RAC)-A sustainable approach for construction industry

With the rapid development of the construction industry which requires an excessive consumption of natural resources and may result in the deterioration of the natural environment, the conflicts between the desire to achieve sustainable development of the construction industry and the shortage of resources will become more and more serious, especially in developing countries like India. At the same time, a large amount of concrete waste is produced from both the construction of new buildings and demolition of old buildings every year. Today, the possibility of recycling construction waste, in particular concrete, has become a major issue around the world. The use of recycled aggregate concrete (RAC) is considered to be an effective measure to develop green ecological concrete and achieve sustainable development in the construction industry. As a result, RAC has attracted increasing interest in both academia and industry. A number of studies have been conducted on RAC especially in relation to understanding the mechanical properties of RAC. The objective of this study was to enhance the understanding of the properties that are associated with concrete and different application areas of RAC.
