とができる。In this way, the asphalt block containing carbon black exhibits good electrical conductivity while maintaining the original performance of asphalt blocks, such as a good walking sensation and resistance to slipping. In addition, it has good workability, and during construction, carbon black is added to the base mortar to make it conductive mortar, and copper wires are placed as a medium at intervals of about 100 to 150 squares to prevent the accumulation of static electricity. Therefore, the electric asphalt block according to the present invention can be effectively used as a flooring material in the above-mentioned places.
