Abstract

Structural concrete is designed to last for decades, and when a concrete structure reaches the end of its life cycle, it must be recycled according to the principle of the circular economic approach. The presented results expand the knowledge required for the re-use of recycled concrete aggregates produced from crushed concrete in concrete and the re-use of recycled concrete fines as cement additive. They represent the importance of selective preparation technology and the role played by the material characteristics of crushed concrete in the development of certain properties of concrete. Knowledge of these relationships is essential, in order for crushed concrete to become a valuable product, instead of ending up as waste.
