Recycled Concrete Aggregate - an overview | ScienceDirect Topics

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.

Recycled Concrete Aggregates: Its Properties & Uses

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.

Carbon Footprint of Recycled Aggregate Concrete

(iii) If we consider the per capita generation average of concrete waste from the construction industry and the population of the region where most of the limestone aggregates in Mexico are produced, the recycling of concrete waste would imply that approximately 22,343 tons of CO 2-e would cease to be emitted annually in this region.
