Dear Colleagues,

In the mid-1990s, reactive powder concrete, which is a precursor of ultra-high-performance fiber-reinforced concrete (UHFFRC), currently available in several countries, was first introduced by French engineers in order to overcome several drawbacks of ordinary concrete, including a low strength-to-weight ratio, high brittleness, and low durability. Based on packing density theory, a very compact mixture was successfully developed, exhibiting a compressive strength over 150 MPa and excellent resistance to permeation of water and gas, enhancing durability significantly. By including high volume contents of fibres, mostly steel fibres, a ductile tensile strain-hardening or deflection-hardening behaviour could also be achieved, leading to very high tensile strength greater than about 8 MPa. Due to its superior mechanical properties and durability, numerous scientists and engineers have conducted various experimental and numerical studies at both the material and structural levels intensively, and this special and novel construction material, called UHPFRC, has been used practically in architectural buildings and civil infrastructure worldwide.

This Special Issue aims to provide a comprehensive overview on the special construction material, UHPFRC, including all aspects related to mechanical properties, durability, bond behaviour, fire resistance, fibre orientation and dispersion, numerical simulation, and structural implications under various loading conditions, such as quasi-static, seismic, impact, and blast. Authoritative review articles and original research papers describing recent findings relevant to material properties and structural implications of UHPFRC for civil and architectural engineering applications are all welcomed.

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.
