Torque–speed relationship in a concrete rheometer with vane geometry
Highlights ► We have proposed torque - speed relationship in concrete rheometer with vane geometry. ► Resistance offered by concrete below and above the vane was considered. ► Resistance from the annulus was also taken in to account. ► The actual flow of concrete was thus represented.
Abstract Derivation of mathematical relationship between torque and speed during shearing in concrete rheometer with vane geometry has been presented in this paper. Resistance offered by concrete below and above the vane as well as effect of concrete resistance from the annulus were taken into consideration to represent actual flow condition of concrete during shearing. An expression for total shear stress has been derived from where shear stress versus torque and shear strain rate versus rotational frequency relationships have been established for the vane geometry of a concrete rheometer.
