Silica fume, also known as microsilica (MS) or
condensed silica fume is a byproduct of the production of silicon
metal or ferrosilicon alloys. Silica fume is one of the most effective
pozzolanic additives which could be used for ultrahigh performance
and other types of concrete. Despite the fact, however is not entirely
clear, which amount of silica fume is most optimal for UHPC. Main
objective of this experiment was to find optimal amount of silica
fume for UHPC with and without thermal treatment, when different
amount of quartz powder is substituted by silica fume. In this work
were investigated four different composition of UHPC with different
amount of silica fume. Silica fume were added 0, 10, 15 and 20 of
cement (by weight) to UHPC mixture. Optimal amount of silica fume
was determined by slump, viscosity, qualitative and quantitative
XRD analysis and compression strength tests methods.
