<p><P>PROBLEM TO BE SOLVED: To provide a quality evaluation method of a new blast furnace slag that establishes a new evaluation index, capable of appropriately evaluating the hydration activity of a blast furnace slag, based on neither the vitrification rate nor basicity, and appropriately manages the hydration activity quality of the blast furnace slag. <P>SOLUTION: In this quality evaluation method of the blast furnace slag, the quality of the blast furnace slag is evaluated as a blast furnace cement admixture, using, as an index, a variable represented by the formula (CaO+SiO<SB>2</SB>)/Al<SB>2</SB>O<SB>3</SB>from the content ratios of calcium oxide, silicon oxide, and aluminum oxide contained in the blast furnace slag. In the variable, CaO, SiO<SB>2</SB>, and Al<SB>2</SB>O<SB>3</SB>show contained mass ratio of each component in the blast furnace slag. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
