<p><P>PROBLEM TO BE SOLVED: To provide a hydration-hardening body which prevents corrosion of a reinforcing bar even under the environment apt to accelerate neutralization and can be used as a structural member having excellent durability for a long period of time. <P>SOLUTION: The hydration-hardening body is produced by: blending a steelmaking slag, fine powder of blast furnace slag, water and further, one or more selected from the group consisting of portland cement, blast furnace cement, fly-ash cement and slaked lime in the range satisfying the formula (1), P+0.6×B+0.85×F+CH≥55; incorporating the reinforcing bars in the resulting blend; and then hardening. In the formula (1): P is the content (kg/m<SP>3</SP>) of portland cement in the blend; B is that of blast furnace cement; F is that of fly-ash cement; and CH is that of hydrated lime. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
