Abstract

To provide a method for estimating the amount of hexavalent chromium elution from solidified soil.SOLUTION: The method of the present invention is the method for estimating the amount of hexavalent chromium elution from solidified soil which is produced by mixing a cement-based solidification material including cement clinker powder, gypsum powder, and blast furnace slag fine powder with sample soil. The method includes: a measurement step for measuring an L-value or / and a b-value in a Hunter Lab color space of the blast furnace slag fine powder; and an estimation step for estimating the amount of hexavalent chromium elution based on the L-value or / and the b-value measured in the measurement step.SELECTED DRAWING: None
