Effects of Concrete Degradation on Gas Transfer Properties

Dear Colleagues,

This Special Issue, “Effects of Concrete Degradation on Gas Transfer Properties”, will address the crucial problem of concrete durability and its degradation due to different causes, such as mechanical, chemical, thermal, etc. From a general point of view, these loadings may lead to changes in concrete mechanical properties and/or transfer properties (gas or water permeability, porosity, diffusivity). These changes are serious issues for structures intended for confining or storage of dangerous materials, immersed tunnel, dams or every structure that must ensure sealing properties. On the other hand, transfer property evolutions (especially gas permeability) are very useful tools to evaluate concrete degradation levels and to provide additional information on mechanical damage, i.e., cracking of materials. As a result, they can help to model or to evaluate material damage. Original papers and studies are solicited on these particular topics. Experiments and modelings, mainly dealing with gas permeability at different scales (structural or material) as well as diffusivity and liquid permeability, in relation to material degradation (cracking, lixiviation, carbonation, etc.), are welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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.
