Ultra-high performance concrete (UHPC) is a novel cement-based composite material. UHPC features superior workability, mechanical properties, flexibility, and durability compared with conventional concrete. However, the challenges, such as the non-universal design methods and test methods, unexplained hydration mechanism, high energy consumption, high autogenous shrinkage, as well as unpredictable durability serving in marine concrete, limit the widespread application of UHPC. The computation and simulation methods of UHPC, as complementary techniques, would help to solve the above challenges. Therefore, this Research Topic has been proposed to highlight and summarize the latest advancements in the computation and simulation methods of UHPC.
This Research Topic will focus on UHPC design, hydration of cementitious in UHPC, novel modeling of UHPC, digital UHPC. We invite researchers to contribute Original Research Articles, Reviews, and Mini-Reviews on themes including, but not limited to:
• The proposal and modification of the UHPC mixture design methods, including novel statistical methods such as deep learning, the optimization of the mesoscale packing structure, the construction of databases.
• The analysis of the UHPC hydration process and the establishment of the multi-scale models during the hydration reaction, including the variation of hydration product components and structural characterization at different scales (microscopic, mesoscopic, and macroscopic) under various complex systems, the effects of disparate cementitious materials on the crystal structure of hydration products, pore structure the systems and hydration degree, innovative detection and systematic theoretical calculation methods, and the multi-level model design (molecular, particle, and structural).
• The enhancement of UHPC performances and establishment of analytical models, including workability in the fluid state, physical characteristics, mechanical properties and volume stability in the hardened state, special properties such as fire resistance, durability, and abrasion resistance, the whole phase analysis of the degradation of cementitious materials, and the analysis models of performances evolution and degradation process under multi-coupling, as an approach in predicting the life cycle properties of UHPC.
