Abstract
Synopsis Apparatus has been developed to measure the flow curve of concretes of medium to high workability. An impeller in the form of an interrupted helix is rotated uniaxially in the concrete by means of a hydraulic transmission and the torque is determined from measurement of the oil pressure. The flow curves conform closely to the Bingham model and, by suitable calibration, it is possible to express values of yield stress and plastic viscosity in fundamental units.
