Use of the ViscoCorder to study the rheology of fresh mortar

Research output: Contribution to journalArticle

Abstract

The ViscoCorder is a small variable speed consistometer that can be used to determine the rheology of fresh mortar. It shows that the downcurve conforms to the Bingham model, and that two parameters, yield value and plastic viscosity, are required to characterize it. When the instrument is calibrated with model fluids these parameters can be calculated in fundamental units. The range of numerical values obtained agrees well with existing data.
