This paper analyzes bend characteristics of hybrid mortar concrete of steel fiber and polypropylene fiber, and discusses whether hybrid reinforced composite material of steel fiber and polypropylene has higher incipient crack strength and toughness. Experimental results show that: bend characteristic of hybrid fiber reinforced mortar concrete is more improved than that of single hybrid fiber reinforced mortar concrete. The composite material of hybrid fiber reinforced mortar concrete can better play the role of steel fiber and polypropylene fiber in reinforcing mortar concrete.
