The marsh cone as a viscometer: Theoretical analysis and practical limits
Abstract In this study, we have investigated the possibility of using the Marsh cone as a viscometer. Rheological measurements along with digital image recording of Marsh cone flow on glycerol-water mixes were carried out. The equations needed to solve the flow problem are written in the case of a purely Newtonian viscous fluid. We show that flow time can be directly linked to the Newtonian viscosity. Flow time is proportional to viscosity. The Marsh cone is then used to test several cement pastes and measured flow time is compared to predicted flow time. The correlation between flow time and cement pastes apparent viscosity stays valid only for no yield stress cement pastes and for flow time higher than about 15 s.
