In order to explore the effect of different types and different content of polypropylene fiber on the mechanical properties of concrete,three different types of polypropylene fiber(wavy polypropylene fiber,em-bossed polypropylene fiber,monofilament polypropylene fiber)are added to the concrete material.The compres-sive strength test,splitting tensile strength test,and axial compressive strength test on polypropylene fiber test block are carried out with different content(0,0.08％,0.11％,0.14％,0.17％,0.20％)as the horizontal vari-ables.The study found that the optimum compressive strength of concrete is when the content of wavy polypro-pylene fiber reaches 0.17％,the optimum splitting tensile strength of concrete is when the content of monofila-ment polypropylene fiber reaches 0.20％,and it has a good effect on the flexural strength of concrete when the content of monofilament polypropylene fiber reaches 0.17％.
