摘要
水泥基材料抗拉强度低、韧性差是其易于开裂、导致结构耐久性低劣的主要原因之一。聚丙烯纤维以其极好的化学稳定性和优良的技术经济性能,在水泥基复合材料中得到日益广泛的应用。本文阐述了聚丙烯纤维增强水泥基材料的特点和主要性能,并对国内外的研究与应用现状进行了综述。
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.
