Document Type and Number:
Japanese Patent JP2017149637
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide slag appropriate for applications such as a road-base material by effective and secure hydration acceleration of steel slag.SOLUTION: A hydration acceleration method of steel slag includes: a crush step 2 of crushing steel slag; a water imparting step 4 of scattering water to the steel slag crushed in the crush step 2 to uniformly impart water to the steel slag; and a steam aging step 3 of steam-aging the steel slag with water imparted at the water imparting step 4.
