Abstract: In regions of heavy snowfall, removing snow requires considerable effort. The heating mortar block system that uses an oscillator with a frequency of 2.45 GHz has been investigated for melting snow. Using this system, snow can be quickly and easily melted. The electric arc furnace oxidizing slag (hereinafter referred to as “slag”) can convert the electromagnetic (EM) waves into heat. Utilizing this property, an EM absorption material used in the heating mortar is mortar mixed with slag as an aggregate (hereinafter referred to as “slag mortar”). The components of the slag vary based on the plant that is being produced. It has been clarified by previous studies that both components and particle sizes of slag affect the EM wave absorption ability of the slag mortar. Therefore, this study attempts to improve the EM wave absorption ability of slag mortar by sintering slag.
