【摘要】 混凝土中加入纤维可以大大增强混凝土的强度,其中聚丙烯纤维增强混凝土复合材料以其优异的性能正得到越来越广泛的应用,研究发现聚丙烯纤维的表面微观结构及其与水泥界面之间粘接力的强弱是影响复合材料性能的重要因素。综述了近年来聚丙烯纤维的表面改性及其在混凝土中的应用。更多还原

【Abstract】 The strength of concrete can be remarkably raised when compounded with fiber and,because ofits excellent property,PP fiber-concrete composites received increasingly wide attention.However the surface treat-ment of PP fiber intending to achieve better adherence to concrete is an important factor that affects property of thecomposite material.In this paper the recent progress in this field is reviewed.更多还原
