Special Issue Information

Dear Colleagues,

Fiber-reinforced composites (FRCs) have been extensively used in various engineering fields worldwide. Numerous researchers and experts are developing and manufacturing high-performance FRCs which are more durable or have improved bonding properties. High-performance FRCs can be used as internal or external reinforcement to prevent structural damage to different concrete structures, including buildings, bridges, parking garages, etc. The development of high-performance FRCs and new applications in the construction sector have attracted great attention in recent decades. Synthetic fibers, chemical fibers, natural fibers, nanofibers, and other fibers are now adopted to produce the high-performance FRCs.

This Special Issue, titled "High-Performance Fiber-Reinforced Composites: Latest Advances and Prospects", focuses on the developments and applications of high-performance FRCs in various engineering fields, aiming at providing a comprehensive background and describing the latest advances and prospects for material engineers, researchers, and experts in civil engineering and material science. The main research areas include but are not limited to the following:

  • Fiber-reinforced cementitious composites;
  • New trends in the design and process methods of FRCs;
  • The modification and process methods of fibers and FRCs;
  • New experimental techniques for FRCs;
  • Mechanical properties, bonding, and durability studies of FRCs;
  • The failure and cracking of FRCs;
  • Case studies of the application of FRCs in various engineering fields;
  • Analytical and numerical models for improving FRC members;

In order to promote the wide application of reactive powder concrete (RPC) in practical engineering. In this paper, RPC was prepared using conventional and economical natural river sand instead of quartz sand and economical and environmentally friendly basalt fiber (BF) instead of steel fiber, and the macroscopic properties of basalt fiber reactive powder concrete (BFRPC) with different fiber content, such as flowability, failure mode, compressive strength and splitting tensile strength were studied, and the strength calculation formula of BFRPC was established based on the mechanical property results. The microscopic morphology and structure of BFRPC were characterized by scanning electron microscope (SEM) and Image Pro Plus (IPP) image processing software. The results show that BF has a small effect on the compressive strength of RPC, while it has a significant increase on the splitting tensile strength. When BF content is at 2 kg/m3, the 28-day compressive strength reaches 95.2 MPa and splitting tensile strength reaches 7.78 MPa. Compared with the RPC with BF of 0 kg/m3, the BFRPC shows an improvement in its 28-day compressive strength by 25.70% and an increase in its splitting tensile strength by 83.92%. According to the microscopic analysis, reasonable fiber content can optimize the internal microstructure of BFRPC, but excessive BF content will produce agglomeration and overlap, resulting in strength loss. Based on the gray correlation analysis method, it was concluded that the particle area ratio and pore fraction dimension were the most correlated with the mechanical properties of BFRPC. In addition, the feasibility and applicability of the BFRPC strength calculation formula were summarized. This research results of this paper provides a valuable reference for the further research and promotion of BFRPC. Full article

The effects of different building materials on sound field characteristics of the concert hall were studied by experimental study and numerical simulations. A single non-directivity excitation sound source in situ test was carried out. The acoustic analysis model of the multifunctional concert hall was established. The reverberation time, the early decay time, the speech transmission index and the sound pressure level (SPL) were tested. The architectural treatment solutions with or without sound absorption in the design ceiling, sound absorption on the side walls, the influence of ceiling form on acoustic characteristics, and the acoustic characteristics of different positions on the first and second floors were analyzed, respectively. Simulation results show that there was little difference in reverberation time at different reception points by using the same treatment solutions, and the speech transmission index increased with the distance of the reception point. The language performance of the positions on the second was better than on the first floor. The SPL decreased with increasing distance from the receiving point. The ceiling form had no significant effects on the acoustic characteristics of the multifunctional concert hall, and the reverberation time was smaller when acoustic materials were used in the ceiling than the side walls. Meanwhile, the language transmission performance in multifunctional concert halls was improved. The difference between the maximum and minimum sound pressure levels for a sound-absorbing material ceiling is less than that of a non-sound-absorbing material. Full article

The sustainability of the construction industry requires new perspectives on existing techniques. For example, fibre concrete has been an integral part of the construction industry for many years and its contribution to enhancing the properties and use of concrete is undeniable, but there are still some questions that need to be answered. The present paper showed the possibilities of statistical evaluation of crack mouth displacement (CMOD) tests performed on 24 fibre concrete specimens. The aim was to point out possible pitfalls and to propose measures based on statistics. The geometrical properties of all samples were determined and correlated with the results of the CMOD test. In this paper, a procedure was considered to compare two different concretes with different fibres at CMOD level. Correlations between geometry and CMOD test results were also demonstrated.

To study the bond–slip behavior of steel–steel fiber recycled aggregate concrete, push-out tests of 16 specimens were carried out using steel fiber volume ratio, steel fiber aspect ratio, steel protective layer thickness and steel embedded length as the design parameters. In addition, the crack patterns, steel strain distribution, and load–slip curves were studied, in addition to the bond strengths of the interface between the steel–steel fiber and recycled aggregate concrete. The results showed that the fracture cracks of the specimens mainly included bond cracks and expansion cracks. For the load increase stage, the maximum strain of the steel flange was near the loading end of the steel and decreased toward the free end, while the strain changed linearly for the load descending stage. The bond–slip process between the steel–steel fiber and recycled aggregate concrete included five stages, which consisted of slight-slip, slow-slip, accelerated-slip, the sharp-slip and load-steep-drop stage, and gentle-slip stage. Additionally, the influencing factors of bond strength were analyzed, where the bond strength increased first and then decreased with increasing steel fiber volume and steel fiber aspect ratios, and the bond strength increased with increasing steel protective layer thickness. The ultimate bond strength decreased slightly with increasing steel embedded length. Finally, the equation for calculating the characteristic bond strength of the steel–steel fiber recycled aggregate concrete was established, which showed that the calculation results were in good agreement with the test results.
