导电混凝土融雪化冰机理分析

Mechlechanism analyzing on deicing or snow-melting of electr ical conductive concrete

本文介绍了导电混凝土的概念及碳纤维混凝土的电热效应 ;从能量守恒的角度分析了导电混凝土融雪化冰的机理及在不同温度、不同结冰厚度、不向降雪量的条件下 ,融雪化冰所需的发热功率。计算结果表明 ,化冰所需的功率P与冰的温度成线性关系 ;融雪时需要的功率较低。

Concept of electrical conductive concrete and electrothermal effect of carbon fiber reinforcedconcrete are introducedi Based on energy conservation law, the mechanism on deicing or snow melting ofelectrical conductive concrete are analyzed and power output required for deicing or snow melting underdifferent temperature, ticckness of ice and grade of snowing are calculated. The calculating results showthat the minilmum power output for deicing is linearly dependent on the temperature of ice;power output for snow melting ts less than that for deicing. Using electrical conductive concrete for deicing or snow melttng is a very effective method. 〔
