Special Issue Information
Dear Colleagues,
With the beginning of the new millennium, the cement and concrete industry has turned towards an eco-sustainable future. Three basic approaches to a sustainable use of concrete have been proposed:
- The reduction of the environmental impact of concrete in terms of CO2 emissions, energy requirements, and natural raw materials consumptions while maintaining an equal or better performance and service life;
- The use of high-performance mixtures at an equal environmental impact and service life;
- The enhancement of durability of concrete at equal environmental impact and performance in order to extend the service life of buildings and infrastructures.
Among the abovementioned approaches, the reuse of industrial byproducts for the production of sustainable mortars and concretes represents an interesting route not only due to the great availability and variety of waste products but also to the environmental benefits arising from the reduction of the raw material consumption, the CO2 emissions, and the energy consumption.
Alkali-activated materials (AAS) and calcium sulphoaluminate cements (CSA) seem to be an environmentally friendly alternative to Portland cements, but their success is strictly related with their performance and durability in aggressive environments. In other words, only if the alternative binders are able to demonstrate adequate properties and durability will their intensive use in the construction sector be possible. Similarly, the use of recycled aggregate as natural aggregate replacement will become estabilished only when durability and performances are adequately investigated.
This Special Issue aims to add evidence to the scientific progress achieved in the research of the performance and durability of sustainable cementitious mixtures.
Topics of interest are related to the properties and resistance in aggressive environments of sustainable cementitious mixtures based on:
- Calcium sulphoaluminate cements;
- Alkali-activated materials;
- Geopolymers;
- Artificial aggregates;
- C&D waste aggregates;
- Industrial byproducts.

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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
