Special Issue Information

Dear Colleagues,

Concrete is a ubiquitous material present in most of our transport infrastructure and buildings, and it therefore plays a crucial role in supporting our economy and everyday lives across the globe. Whilst some countries face the problems of maintaining, updating, and repairing ageing infrastructure, in other regions, challenges emerge in relation to the construction of new structures at a very fast rate. However, today’s new structures will become the ageing infrastructure of the future, which makes the need for concrete structures that last a matter of huge significance. The durability of structural concrete is thus a pressing issue, which has encouraged the development of very interesting research programmes from different perspectives, both in academia and the construction industry.

This Special Issue aims at presenting the latest developments concerned with the durability of cement-based materials in relation to concrete structures, both new and old. Topics of particular interest include:

  • Novel constituents for durable concrete mixes (such as nanomaterials, fibres, or self-healing additives) and their proportioning;
  • Transport properties and their evolution in service conditions;
  • Durability of concrete in the cracked state: Mid-term and long-term evolution;
  • Implications of microstructural changes to durability at the meso- and macroscales;
  • Durability of structural concrete exposed to aggressive environments;
  • Integration of the materials characterization with the challenges of durability, sustainability, reliability, and resilience of concrete;
  • Cement-based materials for the repair and strengthening of concrete structures;
  • Modelling of concrete performance and service life, and integration of durability in the life cycle assessment of concrete.

The abovementioned topics represent only an indicative list, which by no means excludes any other aspects relevant to concrete durability. Many researchers across the globe have been working on very interesting projects which are, in different degrees, aligned with the scope of this call. It would be an honour for me to hear from you, and I would like to take this opportunity to encourage you to respond to this call for papers so we can make this Special Issue a success.

Manuscripts can be submitted until the deadline. All papers will be 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.

This work presents experimental evidence that confirms the potential for two specific zeolites, namely chabazite and faujasite (with a cage size ~2–13 Å), to adsorb small amounts of chloride from a synthetic alkali-activated cement (AAC) pore solution. Four synthetic zeolites were first exposed to a chlorinated AAC pore solution, two faujasite zeolites (i.e., FAU, X-13), chabazite (i.e., SSZ-13), and sodium-stabilized mordenite (i.e., Na-Mordenite). The mineralogy and chemical composition were subsequently investigated via X-ray diffraction (XRD) and both energy- and wavelength-dispersive X-ray spectroscopy (WDS), respectively. Upon exposure to a chlorinated AAC pore solution, FAU and SSZ-13 displayed changes to their diffraction patterns (i.e., peak shifting and broadening), characteristic of ion entrapment within zeolitic aluminosilicate frameworks. Elemental mapping with WDS confirmed the presence of small amounts of elemental chlorine. Results indicate that the chloride-bearing capacity of zeolites is likely dependent on both microstructural features (e.g., cage sizes) and chemical composition. Full article
