Dear Colleagues,

In the new era of sustainable development, durability is a fundamental criterion in the design of reinforced concrete (RC) structures, whereas the majority of the existing building stock presents vulnerabilities due either to the quality of materials or environmental conditions. The corrosion of steel reinforcements is identified as the major degradation factor of RC structures in the long term, with remarkable multifaceted adverse effects which lead to degradation of the serviceability and bearing capacity. In recent decades, significant research has been conducted in order to investigate and quantify the corrosion consequences on reinforced concrete, and there is a growing need for reliable methods of assessing the bearing capacity and remaining service life of corroded structures. In the current international regulations and standards, efforts have been made to factor in corrosion and its impact. Similarly, guidelines are provided on  methods for protection of RC structures, through cathodic protection or corrosion inhibitors, and on estimation of the corrosion level of damaged structures and their remaining lifetime.

This Special Issue of Applied Sciences aims to add evidence to the scientific progress achieved through research in assessing the corrosion damage of reinforced structures.

Topics to be covered in this Special Issue include:

• Monitoring of corrosion level via surface concrete cracking
• Measurement of critical chloride concentration in the laboratory and on site
• Assessment of corroded RC structures
• Modeling the corrosive factor in RC elements
• Coatings to enhance durability of structures exposed to chloride-induced corrosion
• Bond-slip degradation due to corrosion
• Case studies and applications

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.
