2. Ultra-High-Performance Concrete 2.1. Background Over the past two decades, significant endeavors have been dedicated to addressing the brittleness and fragile nature of cement composites, leading to the emergence of a specialized field known as high-performance fiber-reinforced concrete, with Japanese researchers often hailed as pioneers in this domain [41,42,43]. Several noteworthy studies have delved into this type of composite, including the work of Kunieda et al. in 2006 [44].
