3.2.1. Variability and quality control of recycled concrete aggregates A key limitation of recycled concrete aggregate (RCA) is its high variability, stemming from differences in source concrete quality, processing, and contamination. Unlike natural aggregates, properties such as density, water absorption, and strength largely depend on adhered mortar content and parent material characteristics [2, 39]. uncertainty

Although fresh and mechanical aspects have been discussed in detail, durability aspects are limited. The presence of RCA makes drying shrinkage, sorptivity, rapid chloride penetration, and freeze–thaw resistance challenging to control. In practice, the increased porosity and the weaker interfacial transition zone (ITZ) of recycled aggregate may gradually promote the degradation of which cannot be detected by short-term concrete, mechanical
