<p>PROBLEM TO BE SOLVED: To obtain a reformed slag suitably used as the material of construction or the like by fringing the slag obtained by melting and solidifying a waste into contact with a fused material of CaCl2 to improve particle shape, surface condition and hue at the same time. SOLUTION: As the method for reforming the slag obtained by melting and solidifying the waste such as a municipal waste or a sewage or the waste such as a residue generated by incinerating the waste, the slag obtained by melting and solidifying the waste is brought into contact with the fused material of CaCl2 . As the contact method, a method by dipping the slag into the fused material of CaCl2 , a method by sticking the fused material of CaCl2 to the slag and the like are embodied. Since the particle shape, surface condition and the hue are improved at the same time by this way, the slag having properties usable as the material of construction and expected to be used for applications such as an artificial sand (sea side sand) is obtained.</p> |
