Special Issue Information

Dear Colleagues,

This Special Issue aims to present recent advances in fiber-reinforced concrete (FRC), focusing on its mechanical behavior, durability, and structural performance. Topics of interest include innovative fiber treatments, bond mechanisms, FRC performance under extreme environmental or mechanical conditions, and structural applications across various engineering domains. Contributions involving experimental, analytical, and numerical approaches are welcome, as well as case studies and practical implementations.

Ultra-high-performance concrete (UHPC) has been widely investigated for its superior strength and durability; however, despite extensive research on fibre reinforcement, limited attention has been given to validating fibre surface modification strategies at the structural scale. Improvements in fibre–matrix bonding are commonly demonstrated through single-fibre tests, with limited evidence of their translation into the mechanical performance of UHPC elements. This study investigates the influence of bioinspired surface-modified steel fibres on the mechanical behaviour of UHPC, focusing on whether interfacial enhancements lead to measurable structural-scale performance gains. Steel fibres were coated under mild aqueous conditions and incorporated into UHPC at a volume fraction of 1%. Compressive strength was evaluated at 7, 14, 28, 56, and 90 days, while flexural behaviour was assessed at 7 and 28 days using three-point bending tests on notched beams and four-point bending tests on prisms. The incorporation of surface-modified fibres resulted in consistent strength enhancement at all curing ages. Compared with mixes containing uncoated fibres, compressive strength increased by approximately 15% at 7 days and remained 5–7% higher at later ages up to 90 days. More pronounced improvements were observed in flexural performance, with coated specimens exhibiting up to 51% higher peak load at 7 days and 29–32% higher peak load at 28 days in both bending configurations. These results demonstrate that fibre surface modification effectively enhances both early-age and long-term mechanical performance of UHPC, confirming that interfacial bond improvements are directly translated into structural-scale response. The findings highlight fibre surface engineering as a practical approach for improving the mechanical efficiency of UHPC without altering mix composition or fibre dosage. Full article

This study, conducted with a rigorous statistical analysis, aims to assess the applicability of current analytical models in predicting the likelihood of splitting in precast concrete tunnel segments during the thrust phase of tunnel boring. Five analytical models were analyzed and compared to experimental results. The accuracy and precision of the models in predicting the splitting load were evaluated. The study revealed that the prediction accuracy of the models can be affected by various factors, such as the size and geometry of the test specimens and the type of test configuration used. An adjustment to the analytical models with the best performance is proposed to correct for statistical bias and enhance the predictions to address this issue. These findings are significant for the construction industry, as improved cracking control can reduce repair costs. Furthermore, enhancing the predictability of analytical models can improve the safety and reliability of precast concrete tunnel segments during tunnel boring. Full article
