Steam curing effect on the properties of fly ash high performance recycled aggregates concrete [PDF]

open access: yes, 2016
The aim of this study is to encourage the use of Recycled Concrete Aggregate (RCA) in High Performance Concrete (HPC) with fly ash. Three types of coarse RCA sourced from medium to high strength concretes were employed in 100% replacement.
