COMPARATIVE TECHNIQUES FOR MEASURING THE FLOW PROPERTIES OF CEMENT.

Conference Paper


Abstract


  • The most commonly used device for measuring the flow properties of bulk solid materials as relevant to the design of gravity flow hoppers and silos is the direct shear tester. The authors attempt to correlate the flow property design data obtained from this equipment. An extensive series of tests has been undertaken with ordinary portland cement. The purpose of this paper is to present the results of the work obtained for this particular material. Based on experiments it is shown that for practical purposes the unconfined strength of cement as measured by the Walker cell is greater than the, supposedly, same parameter determined by the Jenike machine. In terms of the results the apparent difference in the strength of the cement means that the minimum outlet dimension that is necessary to achieve reliable gravity flow from a hopper will be greater if the Flow Function determined from the Walker cell is used rather than that relevant to the Jenike machine.
