Recycled Concrete Aggregates: A Review | International …
NA generally has low water absorption due to low porosity, but the adhered mortar on RCA has greater porosity which allows the aggregate to hold more water in its pores than NA. Shayan and Xu ( 2003 ) found water absorption values of 0.5–1 % for NA and 4–4.7 % for RCA in the saturated surface dry condition, up to a 4.2 % difference.
