( School of Civil Engieering, Xi' an University of Architecture and Technology, Xi' an 710055, China)Abstract: Deicing salt destruction is the important reason of the concrete premature damage or the failure of durability of concrete in the northem China. The design of fiber concrete in deicing salt environment under the action of an endurance test was introduced, the resistant of deicing salt of properties by different dosage of polypropylene fiber concrete was studied. Through the experiment, it is concluded that the polypropylene fiber concrete in deicing salt under the action of dynamic modulus, quality loss, the flexural strength and splitting tensile strength, the resistant of deicing salt of properties by different dosage of polypropylene fiber concrete is analyzed.
Keyword: polypropylene fiber concrete; deicing salt circulation; resistant of deicing salt
