TL;DR: In this paper, a review of the recent literature within the framework of the CE to explore how its key principles (Reduce, Reuse, and Recycle) apply to the management of C&D waste (C&DW).
Journal ArticleDOI
Mechanical performance of concrete made with aggregates from construction and demolition waste recycling plants
TL;DR: In this paper, the authors analyzed the mechanical performance of concrete with recycled aggregates from construction and demolition waste (CDW) from various locations in Portugal and concluded that the use of RA worsens most of the properties tested, especially when fine RA are used.
Journal ArticleDOI
Assessment of mechanical properties of concrete incorporating carbonated recycled concrete aggregates
TL;DR: In this article, an accelerated carbonation technique was employed to strengthen the quality of recycled concrete aggregates (RCAs) in order to improve the mechanical properties of new concrete, and the experimental results showed that the properties of RCAs were improved after the carbonation treatment.
Journal ArticleDOI
Durability of recycled aggregate concrete prepared with carbonated recycled concrete aggregates
TL;DR: In this article, the durability properties of RAC prepared with non-carbonated and carbonated RCAs, in terms of deformation (drying shrinkage), water absorption and permeability (bulk electrical conductivity, gas and chloride ion permeability), are presented.
