New development of ultra-high-performance concrete (UHPC)

Du, Jiang and Meng, Weina and Khayat, Kamal H. and Bao, Yi and Guo, Pengwei and Lyu, Zhenghua and Abu-obeidah, Adi and Nassif, Hani and Wang, Hao (2021) New development of ultra-high-performance concrete (UHPC). Composites Part B: Engineering, 224:109220. pp. 1-31. ISSN 1359-8368


Ultra-high-performance concrete (UHPC) is a type of cement-based composite for new construction and/or restoration of existing structures to extend service life. UHPC features superior workability, mechanical properties, and durability compared with conventional concrete. However, some challenges limit the wider application of UHPC, such as low workability for large-volume production, high autogenous shrinkage, insufficient flexural/tensile properties, and unpredictable durability after concrete cracking. Therefore, this paper reviews the state-of-the-art technologies for developing UHPC mixtures with improved properties. This review covers the following aspects: (1) the existing design methodologies; (2) the typical ingredients (e.g., binders, aggregates, chemical admixtures, and fibers) for preparation of UHPC and the underlying working principals; (3) the technologies for improving and controlling key properties (e.g., workability, autogenous shrinkage, compressive performance, tensile/flexural properties, and durability); and (4) the representative successful applications. This review is expected to advance the fundamental knowledge of UHPC and promote further research and applications of UHPC.
