PROBLEM TO BE SOLVED: To provide a self-leveling composition used for a floor bed adjusting member and a top end adjusting member, etc., of a continuous footing and having high corrosion resistance to various chemicals. SOLUTION: The self-leveling composition contains 5-70 wt.% (A) alumina cement, 2-40 wt.% (B) a fused slag powder having a CaO/SiO<SB>2</SB>molar ratio of≥1.2, 5-40 wt.% (as solid content) (C) water glass, 5-60 wt.% at least one kind of (D) a fused slag powder having a CaO/SiO<SB>2</SB>molar ratio of 0.10-1.20 and/or (E) an SiO<SB>2</SB>-Al<SB>2</SB>O<SB>3</SB>reactive powder, 5-60 wt.% (F) a reactive siliceous particle having≤3,000 cm<SP>2</SP>/g particle size as specific surface area and 1-30 pts.wt. (per 100 pts.wt. (C) water glass solid content) one or more kinds selected from (G) alcohols and 5-200 pts.wt. (per 100 pts.wt. sum amount of (A)-(G)) (H) aggregate having≤2.5 mm particle size and coarse particle ratio of 1.5-3. COPYRIGHT: (C)2003,JPO |
