Research on the Stressed Performance of Polypropylene Fibrous Concrete Ditch

Abstract:

Polypropylene fibrous concrete is a new kind of composite material. Polypropylene fiber leads to an increase in the resisting strength, cracking resistance performance, resistance to impact performance and permeability reducing performance of the concrete, thus reduces the shrinking and deformation of the concrete. This paper uses the method of numerical analysis, assisted by the software of finite element analysis, makes both static and dynamic analysis on the polypropylene fibrous concrete ditch with different volume mixing. It results in the stress and strain table of the head and base plates of the polypropylene fibrous concrete ditch in the case of 0.1%, 0.5%, and 1% volume mixing of polypropylene fibers. The paper provides technological basis for formation design of the polypropylene fibrous concrete materials, and laids technological foundation for the further developments of polypropylene fibrous concrete in hydraulic engineering.
