The Production Processes and Applications of Geopolymers

Dear Colleagues,

This Special Issue is dedicated to recent advances in the production of geopolymers and their potential applications. In the last few decades, geopolymers have mainly been developed as an environmental friendly alternative for Portland cement. However, in more recent years, they have found a number of new and interesting applications, not always connected with traditional civil engineering. These potential applications can be distinguished as isolation material, modern sorbents, material for lunar or Martian construction, smart materials with phase-change properties, or material for artificial reef building. The possibilities of geopolymer applications seem unlimited, and their use in almost all fields of technology has been noted. These new applications are possible because of improvements in the manufacturing process. New technologies such as additive manufacturing are readily used in geopolymers production. Moreover, recently, a large increase in applications and interest in geopolymeric materials—most often produced from waste materials as a material dedicated for the circular economy—has been observed. Potential topics in this Special Issue include, but are not limited to:

• Additive manufacturing of geopolymers materials;
• Geopolymers as materials dedicated to the circular economy;
• The use of geopolymer materials as a sorbent;
• Manufacturing lunar and Martian shelters based on geopolymer composites;
• Applications in the underwater environment for geopolymer composites.

This Special Issue aims to attract original contributions on topics related to the production of geopolymers and their potential applications. Studies including innovative research and critical analyses related to various types of geopolymers, as well as their methods of production and applications, are welcome, including original articles, case studies, and reviews.

We believe that this collection will summarize the current state-of-the-art and become a source of new ideas resulting in the development of knowledge in the area of geopolymers and their composites.

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. Ceramics is an international peer-reviewed open access quarterly 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 1600 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.
