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.

Recycled Concrete Aggregate an overview ScienceDirect. 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

Development of high strength recycled aggregate concrete
Aug 23, 2022 Much of the inferior properties like increased water absorption, low density, and high porosity of RCAs, are mainly due to this adhered mortar on the aggregate surface. This is one of the main reasons to limit many of the practical applications of RCA, mainly in the production of High Strength Recycled Aggregate Concrete (HS-RAC) [24, 25].

The recycled aggregate controls comparatively fewer bulk density, impact and crushing values, and higher absorption of water in comparison with natural aggregate. The strength of recycled concrete is comparatively fewer, up to 10-14% than natural concrete. The variation turns on to obtained original concrete.

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].
