<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 the reinforcing rod has an oxide layer comprising Fe, P and V on the surface. Alternatively, the reinforcing rod has a silane coupling agent layer on the surface. <P>COPYRIGHT: (C)2008,JPO&INPIT |
