Abstract: Steep increase in population during the 20th century coupled with industrialization and urbanization have resulted in ever increasing construction activity across the globe and unlimited exploitation of non-renewable natural resources like oil or gas, Earth minerals and metal ores, fossil fuels (coal, petroleum, and natural gas). The construction sector is the largest user of natural resources and highest emitter of CO2, 5% of the total GHGs released on the globe, during the cement manufacturing process and hence it plays a major role for achieving the sustainable development of our society. Exploring the new materials that reduces the exploitation of natural nonrenewable resources and emission of GHGs is one of the options available to study. In the context of achieving sustainability in construction, many researchers have explored and recommended the utilization of recycled aggregates from development and pulverization (C& D) waste for new developments in this project work, use of recycled aggregates from C& D waste is studied, which is generated in millions of tones globally every year, for construction purpose. Benchmarking of selection and suitability of recycled aggregates, generated from C & D waste, for its use in construction with parameters that are being studied and reported by various researchers on recycled aggregates, is done with dry density of the recycled aggregate as the base parameter. Studies revealed that the dry density, of the recycled aggregates (RA) and recycled concrete aggregates (RCA), has strong correlation with other major aggregate properties like water absorption, strength (abrasion, impact and crushing) and soundness properties. Thus, the selection criteria of recycled aggregate from C & D waste is simplified.
