Toward Sustainable Construction: Use of recycled aggregate

The current paper aims to discuss the potential of recycling waste concrete to generate recycled aggregates (RA) that may be used as alternative aggregate sources in the production of concrete. Moreover, several major challenges to the use of RA for concrete production are also highlighted.

What are the Different Types of Recycled Aggregate?

The two most common forms of recycled aggregate used in concrete are glass and crushed concrete from previous applications. While other materials such as fiberglass and granulated coal ash have been experimented with, these two products seem to be the most effective recycled material for use in concrete. Some of the criteria that must be met are the recycled aggregate's ability to provide
