Construction and demolition (C and D) waste generation and handling issues have been in focus to achieve sustainable goals. This project comparative studies on C and D waste concrete and Industrial waste concrete in an Aggressive environment. Owing to growth in construction in India, it is appropriate to link generation of C and D waste with the growth. C and D waste in India in 2010 may be estimated as 24 million tonnes. This paper provides an overview of the construction industry in India and gives some statistics about the volume of C and D waste. The main applications of fly ash are then discussed, with particular reference to disposal as well as to civil engineering, chemical industries, agricultural, environmental and soil stabilization applications of fly ash. In future fly ash can be used as a substitute for materials and it remains a potential low-cost adsorbent for the future.
