<p><P>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. <P>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; and blast furnace slag fine powder, and in which the mass ratio of CaO/SiO<SB>2</SB>in the steel making slag is≥1.5 and/or the CaO concentration is≥25 mass%, and further, the surface of the reinforcing rod is subjected to surface treatment. As the surface treatment for the reinforcing rod, iron phosphate treatment, zinc phosphate treatment, zinc calcium phosphate treatment, magnesium phosphate treatment, calcium phosphate treatment or galvanizing is preferably adopted. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
