摘　　要：针对大面积大体积水泥混凝土和沥青混凝土存在的质量通病,通过在普通水泥混凝土和沥青混凝土中掺加少量超高强改性聚酯合成纤维材料和超细晶陶瓷复合材料(以下简称“FC纤维、FC增强剂”),解决了混凝土易开裂、抗冲击韧性差等问题,提高了混凝土道面抗裂、抗冻融、抗盐碱、抗腐蚀、抗冲击、抗磨损、抗疲劳、耐久性、解决大体积、大面积混凝土极易开裂的世界性难题,延长了工程的使用寿命,减少了日常维护工作量。探讨了在类似大型工程中推广使用FC材料的可行性。Aiming at the common quality problems of large-area and large-volume cement concrete and asphalt concrete,in the construction of highway pavement,bridge deck,bridge,tunnel,airport runway,apron,taxiway,water conservancy dam and other projects,by adding a small amount of super-high-strength modified polyester synthetic fiber and ultra-fine grain ceramic composite material(FC material)into the ordinary cement concrete or asphalt concrete,the problems of easy cracking and low impact toughness of concrete are solved.The concrete pavement is crack-resistant,freeze-thaw-resistant,salt-alkali-resistant,corrosionresistant,impact-resistant,wear-resistant,fatigue-resistant,durable,and solves the worldwide problem that large-volume and large-area concrete is easy to crack,extending the service life of the project,reducing the daily maintenance workload.The feasibility of promoting the use of FC materials in similar large-scale projects was discussed.
