摘要
传统水泥基复合材料工艺较为成熟,且具有较为优异的性能,耐水耐火,稳定性好,耐腐蚀性能优越,在建筑工业中广泛应用。然而砂浆混凝土结构下的水泥基复合材料也有明显的缺陷,如功能性单一,脆性大,抗渗能力较差等。为了使得水泥基复合材料可以应用在更多的特殊领域上,新型的水泥基复合材料采用了纤维增强等方式来拓宽应用面。该文简单介绍了目前国内外纤维增强水泥基复合材料的种类,阐述了纤维增强方式和机制,对不同种纤维类型对水泥基复合材料的影响进行了总结和分析,并对未来纤维增强混凝土的发展进行了展望。
Traditional cementitious composites have been widely applied in the construction industry for its mature technics and excellent performance like water and fire resistance,stability and superior corrosion resistance.While,cementitious composites under mortar concrete structure also have some disadvantages,such as single functionalities,brittleness and poor permeability resistance.In order to make cementitious composites can be used in more special fields,fiber reinforcement have been adopted to broaden the application.This paper briefly summarizes the kinds of fibers reinforced cementitious composites,the mechanism of the reinforcement and the effects of fiber to cementitious composites,and provides an outlook on the future development of fiberreinforced concrete.
