The Marsh Cone: A Test Or a Rheological Apparatus?

This article reports on a study of the Marsh cone, a workability test used for specification and quality control of cement pastes and grouts. In the Marsh test, the time needed for a certain amount of material to flow out of the cone is recorded. The longer the flow time, the lower is the fluidity. In this study, the authors show that the flow time can be directly linked to the material behavior, including parameters such as yield stress and plastic viscosity for Bingham fluids. The flow time depends on the tested fluid but is also affected by the cone geometry. A practical application of these results is proposed that does not depend on the cone geometry measurements. Finally, a method using two cones differing by their nozzles is presented. This method allows the calculation of both the plastic viscosity and the plastic yield value. The authors note that this would be a handy on-site control tool to check cement pastes and cement grouts fresh properties.
