Abstract: The effect of replacing part of ordinary Portland cement by granite powder on the electric flux, pore structure, compressive and flexural strength of UHPC under autoclaved curing was investigated. The results show that when part of ordinary Portland cement is replaced by granite powder from 0% to 15%, the electric flux, average pore size and the total pore volume decrease,
and the compressive strength and flexural strength of 7 days and 14 days improve; when part of ordinary Portland cement is replaced by granite powder from 15% to 20%, the electric flux, average pore size and the total pore volume increase, the compressive strength and flexural strength decrease. When 15% of ordinary Portland cement is replaced by granite powder, the pore structure of UHPC is the best and its compressive strength and flexural strength are the
highest.
