N2 - Recycled aggregates RA are obtained from construction and demolished waste, laboratory crushed concrete and concrete waste at RMC plants. The concrete made from recycled aggregate is known as recycled aggregate concrete. The use of recycled aggregate is very beneficial to the environment in civil works.
aggregate and the new concrete made with this recycled aggregate needs new cement. Sand, gravel, limestone and other materials many times are extracted from nature on a destructive way. The recycled aggregate production is about 5 of the total aggregates needed to supply the construction industry.
aggregate physical properties, and, in particular, gradation size control. Establishing a stable production process may reduce variability of the product. EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits.

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 ...
Recycled concrete aggregate as such, holds original aggregate with hydrated cement paste. Hence first, that demolished concrete is cleaned from dirt and other loose particles. After that, it is broken into smaller pieces to produce aggregate known as recycled concrete aggregate. Recycled concrete aggregates are available in size of 20mm to 50mm.
Moreover, when the proportion of recycled aggregates is 30, the concrete mixture obtains quicker its strength compared to conventional concrete. When it comes to long-term performance, tests conducted both 2 and 5 years after the completion of the building and the sidewalk suggest that recycled concrete presents adequate mechanical properties.
