About this Research Topic
With further urbanization and the increase of world’s population nowadays, the constructions of high-rise buildings, long-span highway bridges, and other significant Reinforced Concrete (RC) structures are on the rise. However, these structures face various deterioration mechanisms over their service life because of the environmental effects. Enhancing the ultimate strength and life-cycle performance of these engineering structures is crucial to ensuring safety and durability, minimizing tremendous social and economic losses, and, most importantly, reducing casualties. This imperative underscores the need for investigations into improving the mechanical properties of concrete materials, addressing deteriorated structural resistance, and enhancing the residual strength of RC structures.
Ultra-high-performance concrete (UHPC) stands out as a novel, sustainable, high-performance cementitious composite material with superior mechanical properties surpassing traditional concrete. Given its superior mechanical properties and excellent durability, UHPC has received increasing attention in recent years, and both theoretical researches and engineering applications are constantly advancing. Researchers are dedicated to investigating the mechanical performance of UHPC and the structural behavior of novel UHPC structures.
Within this frame, the objective of this Research Topic is to shed light on the advancements, applications, and construction techniques associated with High-Performance Fiber-Reinforced Concrete (HPFRC) and HPFRC structures. We warmly welcome contributions dealing with:
1. Mix design of UHPC;
2. Innovative concepts to improve the mechanical properties of UHPC;
3. Strength theories and constitutive relationships of UHPC;
4. Bond behavior of UHPC;
5. Thermal properties and fire behavior of UHPC;
6. Structural design and analysis of UHPC structures;
7. Engineering applications of UHPC;
8. Rehabilitation of the corroded RC structures using UHPC, etc.
