Abstract�� The properties of crack resistance,impact resistance, frost resistance and fatigue resistance of cement were improved by adding polypropylene fiber. Mechanism of fiber modifying cement were analyzed. The application of polypropylene fiber in cement was introduced and the development of polypropylene fiber cement was pointed out. Research on high capable, more functional and complex polypropylene fiber modifying cement was important.
