  • Recycled Aggregate - an overview ScienceDirect Topics

    Generally RAs have higher water adsorption than natural aggregates due to the adhered old mortar on their surface. This leads to reduced workability of RAC. However, as the carbonation of RA increases the density of adhered old mortar, the water absorption of the carbonated RA (CRA) is lower, and the workability is improved.

However, as shown in Chapter 5, there is a greater probability of recycled masonry aggregates (RMAs) showing higher water absorption capacity compared with RCA and thus, for a given replacement level, the former is more likely to produce concrete exhibiting greater permeability and sorptivity than the latter

    The study revealed that in most samples, the water absorption of 10 mm aggregates was higher than 20 mm aggregates. It was inferred that smaller size aggregates had more cement mortar which absorbed more water than larger size aggregates. In addition a correlation was found to exist be-tween particle density, porosity and water absorption [5].
