Even though Recycled Concrete Aggregates (RCA) can readily pass the prescriptive requirements for coarse aggregates in structural concrete (ASTM C33 2008), the variability in material properties and quality needs to be quantified and incorporated into design. As a result, no engineering guidelines/standards currently exist for the design and ...
