| Abstract: | In order to improve and control the temperature of concrete shrinkage of the concrete by adding high-intensity,low elongation of the polypropylene fiber.Based on the polypropylene fiber in concrete mechanism of the work to obtain polypropylene fiber crack resistance of the concrete,concrete toughness and impact resistance,impermeability of concrete have varying degrees of increase,particularly concrete-crack performance improved significantly role in the technical and economic conditions permit should be widely used. |
