The Use of Recycled Aggregate Concrete by Mayuri ...

Jul 03, 2019  The results of the study show that the use of recycled aggregate concrete, if manufactured at industrial scale would be more expensive to purchase as a concrete product, compared to natural aggregate. The embodied emissions associated with the production processes does not differ much when the traditional and the alternative product is compared.

FRAMEWORK FOR ANALYSIS OF DEMOLITION SUPPLY CHAIN

Typically concrete waste accounts for 50% of the demolition waste stream (Tam, 2012). When concrete and fines are recycled to produce recycled aggregates (RA) and recycled concrete aggregates (RCA), it goes through a series of processes. At the demolition site the waste needs to be segregated and transported to a recycling facility.

Recycled concrete waste in the form of recycled concrete aggregate (RCA) is presently used mostly as a road base filler in Australia. However, instead of producing natural aggregate (NA) to manufacture natural aggregate concrete (NAC) to use in structural concrete, there is potential to use RCA to manufacture recycled aggregate concrete (RAC).
