PROBLEM TO BE SOLVED : To inexpensively manufacture an earthwork material which effectively utilizes a burned residue such as a domestic waste as the stock, carries a physical aptitude as the earthwork material, suppresses the elution of harmful substances, and keeps a radiation dose abated when containing radioactive substances. SOLUTION : A burned residue containing an unburned matter is immersed in water, drained and air-dried, and this burned residue is mixed with a binder by adding a granular steel slag with a grain size of over 0.1 mm and to 9.5 mm or less to pelletize, and then solidified. An earthwork material can inexpensively manufactured which carries a physical aptitude as the earthwork material, suppresses the elution of harmful substances, and keeps a radiation dose abated when containing radioactive substances. Therefore, the burned residue can effectively be utilized as the earthwork material from an economical view while securing safety. COPYRIGHT : (C)2014, JPO&INPIT
