ECO FRIENDLY RECYCLED AGGREGATES FROM CONSTRUCTION AND DEMOLITION (C&D) WASTE IN CONCRETE - A REVIEW

K. Ramadevi, M. Juhi Hephzibah Shalini and V. Gayathri

Abstract

Huge quantities of construction materials are required in developing countries due to continued infrastructural growth and also huge quantities of Construction and Demolition (C&D) wastes are generated every year in developing countries like India. Construction and Demolition (C&D) Waste is the waste, generated in the construction, maintenance, repair and disposal phases of a building. The disposal of this waste is a very serious problem because on one side it requires huge space for its disposal while on the other side it pollutes the environment. It is also necessary to protect and preserve the natural resources like stone, sand etc. So, the sustainable concept has been introduced in this project work with a concern about the future of our world. This paper reports the results of an experimental study on some of the mechanical properties of Recycled Aggregate Concrete (RAC) as compared to those of the conventional Normal Aggregate Concrete (NAC) with fine aggregate replacement by glass powder. The concrete waste is to be collected from the waste yard, segregated, crushed in jaw crusher, sieved and used. The properties of materials are checked as per Indian standards.
