Special Issue Information
Dear Colleagues,
Reducing the release of CO2 in the production and emission of CO2 is a highly important environmental problem in the production of concrete; there is a need to develop materials that can replace concrete with engineering materials whose production does not have such a heavy burden on the environment. The most promising alternative solutions for the production of Portland cement are technologies of materials production based on alkali activation and geopolymerization. Such materials have a significantly lower carbon footprint than traditional construction materials.
In addition, the above process has another environmental benefit, i.e. the possibility of using anthropogenic raw materials (minerals) such as slags and fly ashes and other wastes for the production. Modern energy, mining, and metallurgical industries produce huge amounts of post-processing waste, whose deposition may cause serious ecological problems related to soil and water contamination. Alkali activation enables one to use such waste as a raw material for manufacturing new products in low energy and low emission processes.
This Special Issue aims to attract original contributions in topics related to the usage of different raw materials for processes of alkali activation and geopolymerization, covering aspects ranging from the preparation of such materials (especially using natural or waste materials), their characterization, and application in different areas, especially in the construction industry.
We believe that this collection will summarize the current state-of-the-art in the field of characterization of raw materials used for alkaline activation and geopolymerization processes, and will become a source of new ideas resulting in the development of knowledge in this area.

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. Crystals is an international peer-reviewed open access monthly 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 2100 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.
