Abstract: The invention relates to processes for making improved ultra-high performance microfiber concrete and articles made from the same. The invention includes blending first dry constituents of fine aggregate, steel fiber, and cement to yield a first homogenous dry mix, optionally adding carbon nanotubes and/or silicon carbide microinclusions, followed by blending with second dry constituents of silica fume, silica flour, and cenospheres to obtain a second homogenous dry mix, followed by adding water only, with further blending, and finally adding a superplasticizer admix and a water-reducing admix to obtain ultra high performance microfiber concrete. The invention also relates to voltage heating for curing and for creating heated UHPC articles.
