| Abstract: | Retarded adhesive mortar is a new type material applied in prestressed concrete components.On the basis of test study, the model of retarded adhesive mortar screw conveying is built by using the theories of rheology. The principle is discussed for retarded adhesive mortar by screw conveying. Meanwhile, the condition of successive conveying retarded adhesive mortar is obtained. The study results in resolving the reliability problem of retarded adhesive mortar screw conveying and laying the foundation for developing the coating device of retarted adhesive prestressed bars. |
| Keywords: | retarded adhesive material screw conveying process analysis prestressed bar coating equipment |
