Recycled Fibers in Fiber-Reinforced Cementitious Composites: Experimental Results and Numerical Modelling

Dear Colleagues,

The use of “green” constituents is emerging as a challenge for enhancing sustainability in concrete production. In this context, the use of recycled fibers is one of the most promising prospects.

This Special Issue aims to collect contributions on the most recent advances about the physical and mechanical characterisation of Fiber-Reinforced Cementitious Composites (FRCC) with Recycled Fibers (RFs). Specifically, it includes (but is not limited to) studies on FRCC produced with Recycled Steel Fibers (RSFs) obtained from waste tires. However, researches on other types of fibers (e.g., made of nylon, plastic, glass, etc.) are of interest, also, as they may shed light on more innovative and less explored possibilities of using RFs in FRCCs.

Moreover, although experimental results are certainly relevant in gaining empirical evidence about the technical feasibility of using a RFs in cementitious composites and its performance with respect to purposely produced “industrial” fibers, theoretical contributions intended at capturing the specific features of RFs and their interactions with cement-matrices are also welcome.

Finally, I hope this Special Issue will provide readers with a selection of papers drawing the current state of knowledge on the use of recycled fibers in cementitous composites.

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. Fibers is an international peer-reviewed open access monthly 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 2000 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.
