Investigation of the Rheological Properties of Microfine Grained Cement and Normal Portland Cement with Silica Fume

Abstract

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.
