In
this experimental study the rheological properties of microfine grained portland
cement and normal portland cement grouts with or without silica fume additives were
to investigated. To estimate the injectability of the cement slurry, we need to
know the rheological properties of the slurry. In the study, microfine portland
cement (DMFC-800), normal portland cement and normal portland cement with 10%
silica fume were used. Marsh funnel, sedimentation and vicat tests are carried
out to determine the rheological properties of these grouts having water/cement
(w/c) ratios of 0.5, 0.75, 1.0, 1.25, 1.5, 2.0, 2.25, 2.5. Obtained results
were compared with between them. It was determined that
grouts prepared microfine Portland cement and Normal Portland cement (NPC) with
silica fume additives have better rheological properties and penetration performance
when compared with the normal portland cements.
