HYDRATED HARDENED BODY HAVING REINFORCING ROD EXCELLENT IN NEUTRALIZATION RESISTANCE AND SALT DAMAGE RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a hydrated hardened body having a reinforcing rod excellent in neutralization resistance and salt damage resistance which can made into a structure member having durability over a long period even under environmental conditions that neutralization is apt to progress.

SOLUTION: The hydrated hardened body, which has the reinforcing rod excellent in neutralization resistance and salt damage resistance at the inside, at least contains: steel making slag; blast furnace slag fine powder; and fly ash, and in which the fly ash content is≥100 kg/m3, and the reinforcing rod is composed of Cr-added steel comprising, by mass,≤0.09% C,≤0.09% N and 4 to 15% Cr. The content of the blast furnace slag fine powder in the hydrated hardened body is preferably 100 to 600 kg/m3.
