Autogenous and drying shrinkage of structural concretes incorporating recycled concrete aggregates from different sources

Abstract: The main relevant difference between recycled concrete aggregates (RCAs) in comparison with the companion natural ones, is the presence of the Attached Mortar content which confers to the RCAs higher porosity and, consequently, higher water absorption capacity. In the last decades, several studies have been performed worldwide for unveiling the role of the employed RCAs on the resulting concrete mixture performances at both fresh and hardened states. On the other hand, the effects of RCA on the early‐age and/o… Show more

“…In addition, there is a great deal of micro‐cracks formed in RCA because of the damage accumulation in the early crushing process of waste concrete. As a result, RCA has the characteristics of large porosity, high water absorption, low bulk density, high crushing index, and high micro‐powder content 6,7 . A large amount of defects is introduced in RAC, which includes the old mortar, more types and larger content of interfacial transition zones 8 .…”

“…Although based on the material cost, the cost of GPC is greatly superior to the CVC due mainly to the used alkali activators and, in addition, fly ash and ground granulated blast slag (GGBS) are hardly available in several regions of the globe, its positive effect to the environment is one of its driving reason for preference over CVC. Thus, researchers try to come up with new sources to be utilized in the construction practice other than CVC and ordinary steel 5–8 . Globally, there are many ongoing research and development studies on the GPC as a promising alternative to CVC 9–13 .…”

“…Thus, researchers try to come up with new sources to be utilized in the construction practice other than CVC and ordinary steel. [5][6][7][8] Globally, there are many ongoing research and development studies on the GPC as a promising alternative to CVC. [9][10][11][12][13] While these studies have mainly positioned on the investigation of thermal characteristics, microstructural properties, electrical conductivity, and durability, some limited research on structural performance has been conducted by testing large-scale structural components.…”
