<p><P>PROBLEM TO BE SOLVED: To provide a method for producing an inexpensive high quality solidified body of steel-making slag without requiring large quantity of cement and solidifying auxiliary materials. <P>SOLUTION: Steel-making slag containing calcium oxide, silicon dioxide, aluminum trioxide, magnesium oxide and phosphorous pentoxide in an amount of≥70% in mass total, and a solidifying auxiliary material or cement are mixed, thereafter, water is added to the mixture and the mixture is solidified. It is more preferable that the steel-making slag with basicity (1) satisfying 2.6 to 3.2 is used, wherein the numerical value dividing the mass total of the calcium oxide and magnesium oxide by the mass of the silicon dioxide is defined as the basicity (1). <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
