摘　　要：微波除冰是一种新型的道面除冰方法,具有加热速度快,不污染环境等特点,但除冰效率低限制了它的使用。在混凝土中掺加碳纤维能提高混凝土的的导电导热性能、耐磨性等,可为道面除冰提供一种新的复合材料。通过掺入不同掺量碳纤维对混凝土进行改性,研究碳纤维混凝土的微波吸热效率、除冰效果及温度空间分布。结果表明,混凝土试件中心点的温度最高,距离中心点位置越远,温度越低;随着碳纤维掺量的逐渐增加,混凝土试件发热效率逐渐增高,碳纤维掺量为2‰时,混凝土试件吸波发热效率最高,与此同时,混凝土试件表面中心点的温度会逐渐增大。Microwave deicing is a new way of deicing,because it is characterized by fast heating speed,no pollution to the environments,and low efficiency.Adding carbon fiber to concrete can improve the conductivity and wear resistance of concrete and provide a new composite material for deicing the pavement.The microwave heat absorption efficiency,deicing effect and temperature spatial distribution of carbon fiber concrete are studied.The results show that the temperature at the center of the concrete specimen is the highest,and the farther the distance is from the center,the lower the temperature.With the increase of carbon fiber content,the heating efficiency of concrete specimens increases gradually.When the carbon fiber content is 2‰,the heat absorption efficiency of concrete specimens is the highest.And at the same time,the temperature at the center of the surface of concrete specimens increases gradually.
