<p><P>PROBLEM TO BE SOLVED: To provide an artificial stone material made of a steel slag hydrated solidified body produced by crushing a steel slag hydrated solidified body and applied as a landfill for sea port or air port construction, riprap or a back filling material. <P>SOLUTION: The artificial stone material steel slag is produced by crushing a steel slag hydrated solidified body. The grain size of the artificial stone applied for the landfill, the riprap and the back filling material is controlled to satisfy that the artificial stone having≤0.8 mm particle diameter occupies≤10 mass% (D<SB>10</SB>≥0.8 mm) as grain size index; the grain size of the artificial stone applied for the landfill, the riprap and the back filling material is controlled to satisfy that the artificial stone having≤2.4 mm particle diameter occupies≤20 mass% (D<SB>20</SB>≥2.4 mm) as grain size index; and the grain size of the artificial stone applied for the landfill, the riprap and the back filling material is controlled to satisfy that the artificial stone having≤4.6 mm particle diameter occupies≤30 mass% (D<SB>30</SB>≥4.6 mm) as grain size index. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
