INSERT AND MANUFACTURING METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide an insert or the like having high strength, dense structure of a cured body and large withdrawal resistance.SOLUTION: There is provided an insert consisting of a cured body of a cement composition containing (A) cement, (B) silica fume, (C) inorganic powder, which have following properties and percentage contents, and an aggregate having maximum particle diameter of 1.2 mm or less, high performance water-reducing agent, an antifoam agent and water. (A) cement: 55 to 65 vol.%. (B) silica fume having BET specific surface area of 15 to 25 m/g: 5 to 25 vol.%. (C) the inorganic powder having 50% volume accumulative particle diameter of 0.8 to 5 μm: 15 to 35 vol.%. Total percentage content of the cement, the silica fume and the inorganic powder is 100 vol.%.SELECTED DRAWING: Figure 1
【課題】本発明は、高強度かつ硬化体の組織が緻密で、大きな引き抜き抵抗力を有するインサート等を提供する。【解決手段】本発明は、下記の特性及び含有率を有する（Ａ）セメント、（Ｂ）シリカフューム、及び（Ｃ）無機粉末と、最大粒径が１．２ｍｍ以下の骨材、高性能減水剤、消泡剤、及び水とを含むセメント組成物の硬化体からなるインサートである。（Ａ）セメント：５５〜６５体積％（Ｂ）ＢＥＴ比表面積が１５〜２５ｍ２／ｇのシリカフューム：５〜２５体積％（Ｃ）５０％体積累積粒径が０．８〜５μｍの無機粉末：１５〜３５体積％（ただし、セメント、シリカフューム、及び無機粉末の含有率の合計は１００体積％である。）【選択図】図１
