As we know that the world’s two most populated countries, China and India. The current population of India is about 1362 million as Thursday, January 31, 2019, 36% of the world’s population. And the population density in India is 460 per km2 (1192 people per m2).Therefore growth rate of population causes the scarcity of land area and environmental degradation. So it required newly constructed house, demolished the old structures, new infrastructure projects by government day by day. Lack of good aggregates is important problem in construction industry. Therefore this paper focuses to comparing the properties of Recycled aggregates and Natural aggregates and gives the interests to Recycled C&D waste and their uses in the construction activities as the resembling strength of natural aggregates
