<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 the reinforcing rod is composed of carbon steel having weather resistance. The reinforcing rod preferably comprises, by mass, ≤0.15% C, ≤0.7% Si, 0.10 to 2.00% Mn, >0.03 to 0.15% P, ≤0.020% S, 0.010 to 0.100% Al, 0.2 to 4.0% Ni, <0.1% Cu and 0.10 to 4.00% Mo. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
