Structural Behaviour of Concrete Waste Materials

Dear Colleagues,

Reinforced concrete produced with waste materials is an environmentally friendly alternative to conventional reinforced concrete that promotes circular economy at a large scale due to the enormous worldwide demand for concrete. Moreover, the concrete industry is interested in ecological solutions due to the societal perception of concrete as a material with a large environmental toll. At the same time, the acceptance of alternative reinforced concrete products requires that their structural behavior is studied so that public safety is ensured.

The structural behaviour of reinforced concrete made with waste materials (as an alternative to raw materials used in the production of concrete, or as an alternative to reinforcement) may differ from that of conventional reinforced concrete. The aim of this Special Issue of Applied Sciences is to provide researchers and practitioners with state-of-the-art knowledge on this issue. The waste may be used for different purposes. The scope includes the replacement of binder, water, fillers, admixtures, aggregates, or reinforcement. The following is a non-exhaustive list of topics covered:

• Structural testing of reinforced concrete made with waste materials;
• Characterization of recycled fibers and their influence on structural behavior;
• Stress–strain modeling of concrete made with waste materials;
• Numerical modeling of the structural behavior of reinforced concrete made with waste materials;
• Resistance models for reinforced concrete made with waste materials;
• Influence of waste materials (e.g., sea or recycled water, alternative binders) on the durability of reinforced concrete;
• Strategies to mitigate the detrimental influence of waste materials on structural behavior;
• Structural design of reinforced concrete made with waste materials.

Original studies and reviews with different levels of maturity are welcome, since the state of the art of reinforced concrete made with the incorporation of waste is highly dependent on the specific waste.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
