Abstract

This paper aims to study the feasibility of highly conductive carbon fiber reinforced concrete (CFRC) as a self-heating material for ice formation prevention and curing in pavements. Tests were carried out in lab ambient conditions at different fixed voltages and then introduced in a freezer at -15 °C. The specimens inside the freezer were exposed to different fixed voltages when reaching +5 °C for prevention of icing and when reaching the temperature inside the freezer, , -15 °C, for curing of icing. Results show that this concrete could act as a heating element in pavements with risk of ice formation, consuming a reasonable amount of energy for both anti-icing (prevention) and deicing (curing), which could turn into an environmentally friendly and cost-effective deicing method.

摘要

本文旨在研究高导电碳纤维增强混凝土（CFRC）作为路面防冰和除冰自热材料的可行性。在实验室环境条件下，于不同固定电压下进行测试，然后将其置于-15°C的冷冻箱中。当冷冻箱内的试件达到+5°C时施加不同固定电压以防止结冰，当达到冷冻箱内温度-15°C时施加不同固定电压以除冰。结果表明，这种混凝土可作为有结冰风险路面的加热元件，在防冰（预防）和除冰（固化）过程中消耗合理的能量，这可能成为一种环保且经济高效的除冰方法。
