Use of RECYCLED AGGREGATES In CONCRETE- A Paradigm Shift
The extensive research on recycled concrete aggregate and recycled aggregate concrete (RAC) as started from year 1945 in various part of the world after second world war, but in a fragmented manner. First effort has been made by Nixon in 1977 who complied all the work on recycled aggregate carried out between 1945-1977 and prepared a state-of-the-art report on it for RILEM technical committee

Recycled Aggregate Concrete: Applications, Advantages & Disadvantages
Recycled aggregate concrete have several reliable applications. However, countries like India need to take some serious urgent measures to unleash the scope of RAC and if done so, concrete recycling will become one of the most important element for construction sustainability.

Improvement of tensile strength with the addition of RCA would usually be associated with an improved elasticity; however, because the “recycled aggregates are more prone to deformation than raw aggregates,” the weakness of the aggregate reduces the Young’s modulus for concrete when RCA is used (Exteberria et al. 2007).

An Overview of Recycled Concrete Aggregate | ETM Recycling
Recycled aggregates are only classified as recycled concrete aggregates (RCA) when the primary material is concrete. By crushing and compressing existing waste concrete and combining it with aggregate, producers can create concrete aggregate to a specific size and quality, which makes it very cost effective to purchase.

Concrete mix with 30% recycled aggregate had the lowest chloride penetration after 2 weeks of saturation and performed better than a concrete mix with 100% natural aggregate. Owing to the lower density and higher water absorption of recycled aggregates, chloride ion diffusion increased with increasing recycled aggregate content beyond 2 weeks.

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.
