Silica fume mixed cement and silica fume as admixture are used for the binder of ultra high strength concrete. In the examination so far, it was confirmed that specific surface area of binder influences. In this study, as a measure to improve fluidity, we focused on limestone fine powder and fly ash2 species, and conducted experiment using mortar as fundamental study. As a result, fluidity was improved by using limestone fine powder or fly ash type2 in inner split. Furthermore, it was confirmed that some formulations using fly ash2 species could secure compressive strength equivalent to that of base mortar.
