Effective Utilisation of Construction and Demolition Waste (Cdw) As Recycled Aggregate in Concrete Construction – A Critical Review
Solid wastes are the inevitable production of the operations of various industries like construction Industry, Machines Manufacturing Units, Textile industry etc. In India the construction industry generates large amounts of waste, which can be composed of different origin materials, most of them classified as non-hazardous. Construction and Demolition waste (CDW) constitutes a major portion of total solid waste production in the world and most of it is used in landfills. Dumping of these construction and demolition waste in landfill causes contamination of soil, water and air from toxic substances. Research by structural concrete engineers has clearly suggested the possibility of appropriately treating and reusing such waste as aggregates in new concrete. The aim of this paper is to explore the separation process of CDW and further use of recycled aggregates from construction and demolition waste (CDW) in concrete mixes. A review of most recent research and legislation applied in India is developed regarding the production of concrete by using these recycled aggregates.
