Research and Application of Modified Polypropylene Fiber Concrete for Water Conservancy and Hydropower Projects
In order to enhance the impermeability and wear resistance of water conservancy and hydropower projects,and to ensure the service life of water conservancy and hydropower projects,this paper takes a reservoir dam in a hydropower hydraulic engineering in an area as an example,and studies the application effect of modified polypropylene fiber concrete.Concrete specimens J1 and J2 were prepared using raw materials such as cement,modified polypropylene fibers,coarse and fine aggregates,and their continuous porosity,wear resistance,permeability coefficient,and splitting tensile strength were tested.The test results show that the J2 specimen with modified polypropylene fiber has better application performance,which can improve the impermeability and durability of concrete,and ensure the service life of water conservancy and hydropower projects.
