Experimental study on mechanical properties of polypropylene fiber concrete
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%.
