Special Issue Information
Dear Colleagues,
Interfacial properties between components in fiber-reinforced cementitious composites (FRCC) are one of the main issues controlling composite behavior, especially when exposed to harsh environments. These interactions contain different regions, including the sand/matrix ITZ and the fiber/matrix interface. Recently, researchers experimentally conducted valuable studies to improve these areas by using novel techniques, such as surface treatments of fiber and sand. The newest method presented by researchers is the nanocoating approach using different nanomaterials. This surface treatment has various advantages in FRCC, including (1) using nanocoating on fiber surface can enhance mechanical characteristics of weak fibers so that the low content of fibers is necessary to obtain specific properties, which is so efficient in FRCC mixtures containing high volumes of fibers, such as ultra-high ductility concrete (UHDC) and 3D printing FRCC; (2) using surface treatments on surface of sand may improve the weak ITZ so that low-quality aggregates can be also used in the construction industries, such as recycled aggregates and ultra-lightweight aggregates; (3) nanocoating techniques can repair surface defects of natural, recycled, and weak fibers to be efficiently used in FRCC mixtures; and (4) using nanocoating method can help to produce a concrete surface with special applications, such as self-sealing, self-cleaning, and superhydrophobic cementitious composites.
Accordingly, this Special Issue (SI) of “Materials” intends to publish experimental, numerical, and review studies on normal or FRCC mixtures using different types of nanocoating techniques. The addressed areas of research include, but are not limited to:
- Strengthening different types of fibers with nanocoating methods;
- Nanocoated sand in cementitious composites;
- Effect of nanocoating on fiber-matrix interfacial properties;
- Thermal conductivity of nano-coated fiber composites;
- Bond strength of nanocoated fibers in cementitious composites;
- The effect of nanocoating techniques on the durability of cementitious composites;
- The optimum dosage of nanomaterials in nanocoating techniques;
- Design of cementitious composites with nanocoated fibers;
- Design of cementitious composites with nanocoated sand;
- Influence of nanocoating on improving the residual strength of thermally damaged concrete;
- Superhydrophobic cementitious composites using nanocoating techniques;
- Anticorrosion nanocoating in cementitious composites;
- Effect of nanomaterial types on the nanocoating technique;
- Self-sealing and self-cleaning nanocoating.

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.
