In order to meet the running needs of the first-stage construction in the middle line of South-to-North Water Transfer Project, the canal lining of both sides of Yellow River Tunnels Project need the use of mechanized equipment construction in order to improve the quality and efficiency of lining construction, there is a need to study the feasibility of the use of polypropylene fiber concrete instead of reinforced concrete in canal lining. This paper analyzes the effect of polypropylene fiber on concrete shrinkage and crack resistance. The results show that all three polypropylene fibers have properties of a low density and high elongation, the dispersivity test results show that dispersivity is better when stirring fiber A after a certain period of time. After the incorporation of polypropylene fibers, the concrete splitting tensile strength is significantly increased, altogether with ultimate tensile value and frost resistance. The incorporation of polypropylene fibers increases the tensile strength of concrete and improve the toughness of it. Compared with standard concrete, the early shrinkage of polypropylene fiber concrete is significantly lower, the incorporation of polypropylene fibers can take the place of steel mesh in concrete cracking, especially in the early control of concrete cracks, it can effectively prevent and suppress the cracks formation and development. This paper recommends the concrete proportioning parameters meeting the requirements of canal lining concrete technology and construction.
