Based on the experimental analyses, the slip phenomenon of CWP flowing in pipes is investigated by tube flow test in different tubes. The origination mechanism and flowing regulation of slip phenomenon in pipes are analyzed and a method of determining the real rheological models of CWP by correcting the influence of the slip is put forward. The results show that all kinds of CWPs behave as the properties of non-Newtonian Herschel-Bulkley fluids in the experimental range and the optimum ratio of coarse powders to the fines in CWP for PFBC are determined.
