초록

This study focuses on the design and performance evaluation of electrically conductive cement-based heating composites system. Conductive fillers, specifically multi-walled carbon nanotube (MWCNT) and carbon fiber (CF), were incorporated to achieve high electrical conductivity. The study demonstrated that localized heating is more economical and efficient than heating entire structures. Experimental results showed stable electrical conductivity and effective heating performance, with localized heating achieving significant temperature increases. The findings suggest that localized heating systems can reduce material costs and energy requirements, highlighting their potential for smart road and de-icing applications. Future research should address long-term performance and economic feasibility.
