The requirement of concrete aggregate in India is large. Corresponding to current annual production of cement of 300 million tonnes, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 MT per year is a safe estimate. Only aggregate from natural sources are allowed in Specifications. Of late, there is difficulty in obtaining natural aggregates for constructions within economic distances. This will help in achieving economy in road construction as well as saving on environment degradation in term of reduced mining and less pollution. Construction and maintenance of roads and highways involve millions of tons of aggregate. Considering the scarcity of fresh aggregate, replacement of part of the fresh aggregate with recycled aggregate is considered in the rural roads. The tests are conducted for various proportion mix of Recycled aggregates and Natural aggregates.M30 grade of concrete is being used for the design. The waste concrete as RCA conserves virgin aggregates, reduces the impact on landfills, decreases energy consumption and can provide cost savings. Recycled aggregates are comprised of crushed, graded inorganic particles processed from the materials that have been used in the constructions and demolition debris. The Techniques of processing C&D wastes, effects of RCA on the properties of concrete and international status of standardization are described. Recent R&D work on use of RCA and fine fractions as replacement of coarse and fine aggregate in high strength concrete is described. This includes novel mixing techniques of virgin and recycled aggregate in concrete mixers.
