Dear Colleagues,

It is a well-known fact that the construction sector, in its broadest sense, is one of the major causes of human environmental impact on the earth. More than one-third of the energy consumed, CO₂ emissions into the atmosphere, and solid waste in the EU are due to the activity of this sector. Cement is the most widely used material in this sector and, at the same time, the cement industry is the largest source of CO₂ emissions in the entire industry, emitting around 800 kg of CO₂ per tonne of cement produced. It is, therefore, an urgent need to decarbonize this activity.

Although most of the environmental impact in this sector occurs during the useful life of the edifice, a significant portion also occurs during the construction and deconstruction of the building. This is where the choice of sustainable and high-performance materials can be a key to reducing the footprint of this activity on the planet. On the other hand, materials composed of a mineral matrix reinforced with sustainable fibers are a very versatile product that can play multiple roles in the building, from pavements, coatings, and roofing plates, to elements for interior partitions. They can also play a very important role in elements of urban implementation, from different types of surface treatments to street furniture. We can also add that it is an affordable product and can provide solutions for housing needs in developing countries or in social housing developments in large cities.

In this Special Issue we aim to provide the latest developments in research on sustainable composite materials of the mineral matrix (and, therefore, gypsum, lime, cement of all kinds, geopolymers, etc.), reinforced with any type of fiber. We want to know and collect a representative sample of the materials being developed in the laboratory as a sustainable alternative to existing products on the market, which could be replaced due to their good outputs.

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. Materials 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 2600 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.
