METHOD FOR PREDICTING SIGN OF SOLIDIFICATION OF GRANULATED BLAST FURNACE SLAG

Title:

METHOD FOR PREDICTING SIGN OF SOLIDIFICATION OF GRANULATED BLAST FURNACE SLAG

Document Type and Number:

Japanese Patent JP2017075900

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method for predicting a sign of solidification of a granulated blast furnace slag more easily and more rapidly to efficiently prevent solidification of a granulated blast furnace slag by bringing a solidification inhibitor into the granulated blast furnace slag.SOLUTION: The above object is achieved, by measuring the concentration of the eluting solidification inhibiting active ingredient of a solidification inhibitor when a granulated blast furnace slag contacting with the inhibitor is immersed in water and predicting a sign of solidification of the granulated blast furnace slag based on the measured concentration.SELECTED DRAWING: None
