Present State of Application and Research on Performance of Polypropylene Fiber Reinforced Cement-based Material |
| |
| Abstract: | Low tensile strength and bad ductility of Cement-based materials are the dominant reasons for incidental crack and deterioration of durability for reinforced concrete(RC) structures. For its perfect chemical stability and excellent economic and technical performance, Polypropylene fiber has an extensive application in cement-based composites. This paper elaborated the characteristics and main performance of polypropylene fiber reinforced cement-based materials, and summarized its present research and application condition in domestic and overseas. |
