MANUFACTURING METHOD OF CEMENT HARDENING BODY USING CEMENT COMPOSITION
PROBLEM TO BE SOLVED: To provide a cement composition having high flowability (for example 0 hit flow value of 200 mm or more) before curing and exhibiting high compressive strength (for example 350 N/mmor more) after curing.SOLUTION: There is provided a cement composition containing cement, silica fume with BET specific surface area of 15 to 25 m/g, inorganic power with 50% cumulative particle diameter of 0.8 to 5 μm, an aggregate A with maximum particle diameter of 1.2 mm or less, a high performance water-reducing agent, an antifoaming agent and water, with percentage of the cement of 55 to 65 vol.%, percentage of the silica fume of 5 to 25 vol.% and percentage of the inorganic powder of 15 to 35 vol.% in total amount 100 vol.% of the cement, the silica fume and the inorganic powder.SELECTED DRAWING: None
【課題】硬化前には高い流動性（例えば、０打ちフロー値が２００ｍｍ以上）を有し、かつ硬化後には高い圧縮強度（例えば、３５０Ｎ／ｍｍ２以上）を発現するセメント組成物を提供する。【解決手段】セメント、ＢＥＴ比表面積が１５〜２５ｍ２／ｇのシリカフューム、５０％累積粒径が０．８〜５μｍの無機粉末、最大粒径が１．２ｍｍ以下の骨材Ａ、高性能減水剤、消泡剤及び水を含むセメント組成物であって、セメント、シリカフューム及び無機粉末の合計量１００体積％中、セメントの割合が５５〜６５体積％、シリカフュームの割合が５〜２５体積％、無機粉末の割合が１５〜３５体積％であるセメント組成物。【選択図】なし
