Special Issue Information
Dear Colleagues,
The quality of the environment is influenced to a significant extent by cement manufacture. On the one end, cement production is one of the largest consumers of fuel and raw materials and represents one of the major industrial sectors giving rise to carbon footprint. In 2019, worldwide production of cement was estimated at 4.10 billion tonnes, generating about 8% of global anthropogenic CO2 emissions. In this regard, the main challenge for the cement industry is focused on a strong carbon dioxide emissions reduction. On the other hand, the cement industry traditionally plays a leading role in waste utilization and can make an important contribution to the protection of the environment. Both ordinary and special cements are able to absorb huge amounts of industrial wastes in their manufacturing process as a constituent of the final product or as a component of the raw feed. The first use deals with fillers (added in small quantities to the clinker without significantly affecting the cement performance) and active components (commonly added in considerable amounts for improving the technical behaviour and decreasing the clinker concentration). Regarding the second utilization, to date the use of solid residues as raw mix components for the cement kiln has received comparatively little attention from researchers and engineers; however, there is an increasing interest in new wastes for the synthesis of ordinary and/or special cements. This Issue is aimed at giving an overview dealing with the use of industrial wastes as raw materials and/or constituents of ordinary and special cements.

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. Applied Sciences 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.
