ABSTRACT:
A manually held device for measuring and indicating slump of flowing concrete material being discharged from a concrete mixer along a discharge chute in which a torque responsive member is contained within a manually held housing, a sensing assembly is connected to the torque responsive member and extends beyond the housing for at least partial immersion in concrete material flowing in a discharge chute. The sensing assembly includes diametrically opposite sensing members of different size adapted to turn about the axis of the torque responsive member to produce torque forces of different magnitude and direction, the resultant of said forces being transmitted to the torque responsive member, and indicating means on said housing and associated with the sensing assembly for showing measurement of the slump or consistency of the flowing concrete material. A method of measuring and indicating the consistency of a concrete mass by positioning a sensing means in the flowing mass of concrete material with the axis of the sensing means generally normal to the flow direction of the concrete material and applying resultant torque forces imparted to the sensing means by the flowing concrete material to a torque transmitting means, and indicating the magnitude of the resultant torque force on a scale calibrated in terms of inches of slump.
