Microcosmic Analysis on Bonding Performance of Polypropylene Fiber Concrete

Abstract:

In the process of pull out testing polypropylene fiber, the performance of bonding of tested and untested objects has been microscopically analyzed; both the interface of polypropylene fiber-cement-based material, the hole morphology of cement-based material after the polypropylene fiber being pulled out by force and the condition after the polypropylene fiber being pulled out of concrete-based material are observed. Attachment phase analyses of the surface of the polypropylene fiber and cement-based transverse cracks after the polypropylene fiber being pulled out have both confirmed the fact that the performance of bonding of the polypropylene fiber-cement-based material can effectively transmit the outer force borne by the polypropylene fiber and that the performance of bonding of the polypropylene fiber-cement-based material is better.
