	  abstract     = {Silica fume, also known as microsilica (MS) or 
condensed silica fume is a by-product 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.
