Special Issue Information
Dear colleagues,
During the 20th century, the yearly carbon dioxide (CO2) emissions rose from 1500 to 25000 Mton. These emissions are caused by many activities, including construction that, due to cement production alone, contributes with more than 6% of this value. The Paris Agreement has established the urgent need to fight climate changes happening to the planet.
Today, one of the main objectives of this sector is to provide the construction industry with a new way of producing structural concrete with a positive environmental impact throughout its life cycle. To achieve that, synergies between three vectors need to be developed: replacement of concrete’s traditional binder with one of lower environmental impact; use of recycled aggregates (RA) instead of natural ones; and reuse of alternative water instead of tap water.
This Special Issue focuses on the development of sustainable cementitious composites, either through the replacement of natural aggregates with recycled aggregates, or the use of alternative sustainable binders to Portland cement or the use of reused water.
The main topics covered in this Special Issue include (but are not limited to):
- Experimental characterization of cementitious composites containing recycled aggregates from all origins;
- Experimental characterization of cementitious composites containing alternative sustainable binders;
- Experimental characterization of cementitious composites containing recycled water;
- Development of analytical methods and numerical models applied to the characterization of sustainable materials and structures produced with them;
- Development of standards or specifications for evaluating the performance of sustainable materials;
- Development of a environmental and economic assessment of sustainable mixes and structures with them;
- Development of large scale models of sustainable materials, measuring the impacts of these new materials.
Original studies and reviews on subjects other than the aforementioned that are deemed to contribute to an advance in the knowledge of the sustainable materials and their applications are welcome in this Special Issue.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Sustainability 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.
