<p><P>PROBLEM TO BE SOLVED: To provide a method for producing modified granulated blast furnace slag by modifying the granulated blast furnace slag that is stored in an outdoor yard and deteriorated, and to provide a method for producing blast furnace cement, which is a new use of the modified water-granulated blast furnace slag and with which blast furnace cement is produced by using the deteriorated granulated blast furnace slag. <P>SOLUTION: The method for producing modified granulated blast furnace slag comprises a step of bringing the deteriorated component-stuck granulated blast furnace slag into contact with dilute sulfuric acid. The method for producing blast furnace cement comprises the steps of: preparing the modified granulated blast furnace slag by bringing the deteriorated component-stuck granulated blast furnace slag into contact with dilute sulfuric acid; and producing the blast furnace cement by using the modified granulated blast furnace slag. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
