The relevant experiments illustrates a . c . power is more suitable for deicing or snow - melting than d . c . silica fume can improve the dispersion of carbon fibers and then reduce the electrical resistivity of carbon fiber cementious composites . at a certain volume content , when the ratio of cement , sand and stone is l : l : 2 ( by weight ) , the properties of the cfrc is the best on the whole . ( 4 ) a self - adaptive fuzzy controller is designed to finish the total control procedure after considering all kinds of factors 大量实验研究发现：采用交流电是碳纤维导电混凝土用于融雪化冰时的最佳电源选择；采用硅灰能较好地提高碳纤维在基体中的分散性，有效降低碳纤维水泥基复合材料的电阻率；并在现有的级配比实验中发现了具有最好综合性能的配比，即在相同的纤维体积含量的情况下，导电混凝土的具有最好综合性能的配比是水泥、砂子、石子的重量比为1 : 1 : 2 。
