Abstract: The present invention relates to the manufacture and use of off-specification fly ash (OSFA), which would have otherwise been landfilled, in preparing ultra-high-performance concrete (UHPC). The present invention aims to provide a new avenue for valorization of OSFA in the concrete industry by utilizing high-volume OSFA in producing UHPC. Compared with conventional concrete and high-performance concrete, UHPC is a family of advanced concrete featuring exceptional compressive strength, ductility, and long-term durability. Application in UHPC is expected to be a new and feasible technology to efficiently recycle OSFA.
