Lately, electrically conductive concrete (ECC) is being investigated to prevent accumulation of snow and ice. The conductivity of electrical conductive concretes containing steel fiber is reduced by the corrosion of the steel fiber in time. Therefore, it is proposed to produce electrical conductive concretes that does not contain steel fibers recently. In this study, it is aimed to examine rebars in electrical conductive concretes non containing steel fiber. For this, 45 ´ 45 ´ 5 cm ECC slabs with and without Փ10 rebars were produced. Carbon fiber was used as a single fiber type in the mixtures. The heating times and thermal behaviors of the slab specimens were examined in a cooler at about – 10 °C. According to the results, the temperature in the rebars reinforced specimens has increased first in the regions near the electrodes and then proceeds towards the middle of the specimen. In non-rebars specimens, temperature rise has started from random points.
