Abstract
In order to study the application effect of polypropylene fiber in improving the performance of concrete,the differences of splitting tensile strength,flexural strength and compressive strength of polypropylene fiber concrete with different dosage were tested and analyzed.The results show that the properties of concrete are improved by adding polypropylene fiber.When 3%polypropylene fiber is added,the splitting tensile strength of concrete increases most obviously,when 2%～3%polypropylene fiber is added,the bending strength of concrete increases most obviously,and when 3%～4%polypropylene fiber is added,the compressive strength of concrete increases most obviously.In summary,it is recommended to use 3%polypropylene fiber content,at this time the mechanical properties of concrete are at a higher level.关键词
