Postponed-set mortar (PSM) is a new type material applied in prestressed concrete components. Successive coating a lay of PSM on prestressed strand is a key to engineering application. On the basis of experimental investigation, the model of PSM screw conveying is built by using the theories of rheology, and the flow for PSM in a single-screw coating machine is studied. The experimental results suggest that the Bingham plastic’s PSM can be conveyed by screw and coated on prestressed strand. It is achieved that PSM and polyethylene sheath is automatically and successively coated on prestressed strand only once by using the machine.
