The utilization of recycled concrete aggregate to produce ...

Sep 01, 2009  Recycled concrete aggregate (RCA) is an example of a common construction waste that is produced from demolishing concrete structures as they approach the end of their service life. Supplementary cementing materials (SCM) such as fly ash and slag are industrial by-products, which have a long history of use with Portland cement (PC) in concrete.
