An overview of microstructural and material properties of ultra-high-performance concrete

Concrete being the most-commercialized construction material, plays an indispensable role in the performance of many industrial, commercial, military, and residential structures. Hence, the evolution in the quality of concrete lead to the development of one of the most efficient and beneficial type, namely ultra-high-performance concrete (UHPC). In this article, a comprehensive literature review has been conducted to highlight the manufacturing principles and properties of UHPC. The affluent production of UHPC depends upon its compositional materials, water-to-binder ratio, and the mix design approach. This review also divulges that the curing conditions, aggregates and fiber properties, specimen size and the strain rates are the key factors in controlling the mechanical and durability properties of UHPC. Moreover, along with its various properties, attempts have been made to address the current challenges and their solutions so far, for their widespread economical usage.
