Abstract:
Provided is a cement composition that has high fluidity (for example, a 0-drop flow value of 200 mm or more) before curing and exhibits high compressive strength (for example, 320 N/mm 2  or more) after curing. The cement composition includes a cement, a silica fume having a BET specific surface area of from 10 m 2 /g to 25 m 2 /g, an inorganic powder having a 50% cumulative particle size of from 0.8 μm to 5 μm, a fine aggregate having a maximum particle size of 1.2 mm or less, a water reducing agent, an antifoaming agent, and water. The ratio of the cement is from 55 vol % to 65 vol %, the ratio of the silica fume is from 5 vol % to 25 vol %, and the ratio of the inorganic powder is from 15 vol % to 35 vol % in the total amount of 100 vol % of the cement, the silica fume, and the inorganic powder.

Claim (Index 1):
A method of producing a cementitious cured body made of a cement composition, the cement composition comprising:\n cement; silica fume having a BET specific surface area of from 10 m 2 /g to 25 m 2 /g; an inorganic powder having a 50% cumulative particle size of from 0.8 \u03bcm to 5 \u03bcm; a fine aggregate having a maximum particle size of 1.2 mm or less; a water reducing agent; an antifoaming agent; and water, wherein a ratio of the cement is from 55 vol % to 65 vol %, a ratio of the silica fume is from 5 vol % to 25 vol %, and a ratio of the inorganic powder is from 15 vol % to 35 vol % in a total amount of 100 vol % of the cement, the silica fume, and the inorganic powder, the method comprising: a molding step of setting the cement composition into a mold to provide an uncured molded body; a room temperature curing step of subjecting the uncured molded body to sealed curing or atmospheric curing at from 10\u00b0 C. to 40\u00b0 C. for 24 hours or more, followed by demolding the molded body from the mold, to thereby provide a cured molded body; a water absorbing step of immersing the cured molded body into boiling and non-pressurized water, and then cooling the water to 40\u00b0 C. or less while keeping the cured molded body immersed in the water; a heat curing step of subjecting the cured molded body after being immersed in the water to steam curing or hot water curing at from 70\u00b0 C. to 95\u00b0 C. for 24 hours or more, to thereby provide a cured body after heat curing; and a high-temperature heating step of heating the cured body after the heat curing at from 150\u00b0 C. to 200\u00b0 C. for 24 hours or more, to thereby provide the cementitious cured body.
