( Shanghai Electronic Engineering Design and Research Institute CO. ,LTD., Shanghai 200023, China)Abstract: This paper analyzes the reasons of crack for steel-concrete composite floor, and describes the anti-crack effect of polypropylene fiber in concrete. During the description, the paper quote some engineering examples to prove the real effect of anti-crack measures for composite floor. In conclusion, it has more better anti-crack effect for compositive measure when concrete mix with low quantity of polypropylene fiber.
Keywords: polypropylene fiber; composite floor; restraint stress; crack; fiber concrete
