The paper explores the flow for retardedadhesive mortar with Bingham liquid in a single-screw ectruder on the basisof test. By using the theories of rheology, the model of retarded adhesivemortar screw conveying is built. Discussed the principle for retardedadhesive mortar by screw conveying, the condition of successive conveyingretarded adhesive mortar is obtained, i.e. the screw revolutions must exceedthe critical revolutions. The test results suggest that it can be relizedsuccessive conveying and coating for retarded adhesive mortar with Binghamliquid in the mechanism of retarded adhesive mortar screw conveying andcoating, when the screw revolutions are within 78∼240\,r/min. Thefindings of these investigations resolve the reliability problem of retardedadhesive mortar screw conveying and lay the foundation for developing thecoating device of retarted adhesive prestressed strand.
