To predict the behaviour of grouting material you need to know rheological model and properties. In this context, rheological properties of the microfine cement (Rheocem 900) grouts were investigated. Bleeding, Marsh cone flow meter and Vicat tests are carried out to determine the rheological properties of microfine cement grouts having water/cement (w/c) ratios of 0,8, 1,0, and 1,2. Obtained results were compared with rheological properties of microfine cement grout having with w/c ratio of 1,0 prepeared with super plasticizer. It was determined that grouts prepeared with super plasticizers have better rheological properties and penetration performance when compared with grouts prepaired without super plasticizer.
