ABSTRACT
In the last decades recycled concrete was widely investigated. The reuse of crushed cementitious aggregates allows to close a loop towards a circular economy. In this concern, the cement-based materials are particularly important, because of their worldwide use. The addition of recycled concrete aggregates to produce new concrete is done for many applications in the building sector. Properties such as the compressive strength or the durability issues are attained with an adequate mix proportion and quality of the components. On the other hand, the concrete produced with mixed granulates, such as ceramics, stone and cementitious wastes as main ingredients, still remains an issue to clarify. This work analyzes the main inert components that may be collected in regional recycling centers and preliminary reviews the properties and the durability of recycled concrete that may be produced with a variable content of the components. This allows to better identify the possible uses of such recycled concrete for the infrastructures: embedding, support, basements, or structural.
