CEMENT BASED FILLER
To provide a cement based filler of two-liquid type which makes it possible to control arbitrary gelation time and reduce lateral pressure even if setting a high loading speed, and which exerts no hindrance on curability after filling.SOLUTION: A cement based filler of two-liquid type is composed of a slurry A including calcium aluminates, plaster, a light-weight extender, a separation reducing agent and a setting modifier, and a slurry B including cement. Viscosity of the slurry A is 8500 mPa s or less, viscosity of the slurry is 2500 mPa s or less, and a viscosity ratio of the slurry A and the slurry B (the viscosity of the slurry A/the viscosity of the slurry B) is 0.1 to 50.SELECTED DRAWING: None
【課題】２液タイプのセメント系充填材であって、任意のゲル化時間の調整が可能であり、充填速度を高く設定しても側圧を抑制でき、充填後の硬化性にも支障を及ぼすことのない充填材の提供。【解決手段】カルシウムアルミネート類、石膏、軽量増量材、分離低減剤及び凝結調整剤を含有するスラリーＡと、セメントを含有するスラリーＢからなり、スラリーＡの粘度が８５００ｍＰａ・s 以下、スラリーＢの粘度が２５００ｍＰａ・s 以下、かつスラリーＡとスラリーＢの粘度比（スラリーＡの粘度／スラリーＢの粘度）が０．１〜５０である２液タイプのセメント系充填材。【選択図】なし
