Special Issue Information
Aim and Scope: Sustainability requires a judicious use of natural resources. Reducing the consumption of natural aggregates and ensuring adequate durability of reinforced concrete infrastructures are major steps towards sustainability. Performance-based Service Life Design and recycled aggregate concrete are intense research fields. Considering the research maturity of each subject on its own, it is time to couple them and deliver knowledge on performance-based Service Life Design for reinforced concrete structures incorporating recycled aggregates. This Special Issue of Materials International constitutes a way to disseminate results and findings from original studies, experimental programs, empirical, analytical and numerical modelling of initiation period (carbonation- and chloride ion-related), propagation period or both (service life). Probabilistic, semi-probabilistic and deterministic approaches are welcome.
Subtopics: Initiation period – carbonation-induced corrosion; Initiation period – chloride-induced corrosion; Propagation period – carbonation-induced corrosion; Propagation period – chloride-induced corrosion; Service life models.
Keywords: durability; corrosion; reinforced recycled aggregate concrete; Service Life Design; carbonation; chlorides; performance indicators

Abstract: Recently, numerous programs on the mechanical behaviors and durability of recycled aggregate concrete (RAC) blocks/bricks have been conducted in China as well as the structural performances of RAC masonry structures. In addition, several practical engineering applications of RAC blocks/bricks were also implemented. The extensive review and thorough assessment of recent research progresses on RAC blocks/bricks in China are presented. Firstly, the production of RAC blocks/bricks, the mechanical behaviors and durability of RAC blocks/bricks are summarized, highlighting the governing variables. Secondly, the mechanical properties, in terms of compressive and shear performances, of RAC block/brick masonry are reviewed. The test results obtained from open literatures are employed to derive the prediction models for RAC masonry. Then, a review on seismic behavior of RAC masonry walls is presented as well as some research progress of life cycle assessment (LCA) of the production of RAC blocks/bricks. At last, a brief introduction to several practical applications of RAC blocks/bricks in China is presented. The need for further study is proposed at the end of the paper. Results of these studies show that it is feasible to manufacture concrete blocks/bricks with recycled aggregates and apply RAC blocks/bricks in practical engineering, which will significantly improve the sustainability aspect of masonry structures. It is hoped this review will improve the practical engineering applications of RAC blocks/bricks.
