The world’s waste production is at its highest level ever following the development of new world powers. This is particularly evident in construction/demolition activities, which have one of the largest contributions to economic growth and waste generation, therefore requiring stricter policies to encourage sustainability.

Concrete is the favorite choice as a construction material among civil engineers around the globe for decades, due its better performance, longer life, and low maintenance cost. However, the continuous necessity and increase of raw materials of concrete, especially coarse aggregate, due to a rapid building construction, tends to increase the danger of early exhaustion of natural resources. Recycled coarse aggregate plays a great role as an alternative raw material that can replace the natural coarse aggregate for concrete. With the wave of sustainability of construction new sustainable and reusable construction materials are needed. One such material is recycled aggregate concrete.

We invite researchers to contribute original research articles as well as review articles that will stimulate continuing efforts to understand the recent advances and innovations in these research fields. We are particularly interested in articles describing the recent trends, developments, and applications of recycled aggregates on concrete structures and elements, namely, their characterization and application; performance in aggressive environments; durability and life cycle assessment of recycled aggregate concrete; and so forth. Recent advances in recycled aggregate concrete, their applications, and limitations are welcome.

Potential topics include but are not limited to the following:

• Recycled aggregates production methods and classification
• Recycled aggregates: characterization, mesostructure analysis, and applications
• Mechanical properties of concrete containing recycled aggregates
• Development of design methods and models for recycled aggregate concretes
• Performance of recycled aggregate concrete in aggressive environments
• Hygrothermal and mechanical behavior of concrete blocks with recycled aggregates
• Effect of recycled aggregates on the fracture behavior of concrete
• Durability and life cycle assessment of recycled aggregate concrete
