Abstract
A sidewalk tile with snow-removal function is stably obtained that is capable of being heated to a desired temperature, while at the same time sufficiently maintaining strength. A heat-generating concrete body is obtained by mixing particle-form (granular) or powder-form carbon material with un-hardened concrete at a specified ratio, and then pressing it with a high-pressure press at a pressure of approximately 980 kN to remove moisture and to form it into a tile shape. A pair of electrodes are embedded in end sections on both ends in the width direction of the heat-generating concrete body. The outer surfaces of the heat-generating concrete body are covered with an insulation-coating layer. One side and the circumference of the heat-generating concrete body are covered with un-hardened concrete and formed into a single tile shape by pressing with a high-pressure press to obtain a sidewalk tile with the snow-removal function.
