Recycled Concrete Aggregates: A Review SpringerLink
29.03.2013· The aggregate characteristics of density, porosity, and water absorption are a primary focus in determining the proper concrete mix. These characteristics should be known to limit absorption capacity of aggregates to no more than 5 % for structural concrete, and thus the proportion of RCA is often limited in concrete mixes (Exteberria et al. 2007), as is discussed later in this paper.
