Document Type and Number:
Japanese Patent JP4427375
Kind Code:
B2
Abstract:
To provide such a technology that the neutralization resistance of a hardened body obtained by using mixed cement, especially, blast furnace cement is made equal to or higher than that of a hardened body obtained by using portland cement, and a large amount of recycled material can be used.
In concrete obtained by using blast furnace cement having excellent neutralization resistance, aggregate having an elution pH value of ≥12 is used and steel-making slag is used as the aggregate having an elution pH value of ≥12. Further, the steel-making slag treated by steam-aging is used as the aggregate having an elution pH value of ≥12.
