GROUT MATERIAL, GROUT MORTAR COMPOSITION, AND CURED BODY
To provide a grout material, a grout mortar composition, and a cured body that reduce heat of hydration and drying shrinkage and enhance filling property without using too much water reducing agent.SOLUTION: A grout material contains cement, an expanding admixture, a gas foaming substance, a water-reducing admixture, fine aggregate A, and fine aggregate B. The fine aggregate A has a particle size of less than 1.2 mm and an average particle size of 0.4-0.8 mm. The fine aggregate B has a particle size in the range of 1.2-10 mm and an average particle size of 2-9 mm. A mass ratio (fine aggregate A/fine aggregate B) of the fine aggregate A to the fine aggregate B is 50-200% and an angle of repose is 40-55°.SELECTED DRAWING: None
【課題】水和熱、乾燥収縮を低減し、かつ、減水剤を過多とせずに充填性を高めたグラウト材料、グラウトモルタル組成物及び硬化体を提供すること。【解決手段】セメント、膨張材、ガス発泡物質、減水剤、細骨材Ａ、細骨材Ｂを含有するグラウト材料であって、前記細骨材Ａの粒子径が１．２ｍｍ未満であって、平均粒子径が０．４～０．８ｍｍであり、前記細骨材Ｂの粒子径が１．２～１０ｍｍの範囲であって、平均粒子径が２～９ｍｍであり、前記細骨材Ａと前記細骨材Ｂの質量比（細骨材Ａ／細骨材Ｂ）が５０～２００％であり、安息角が４０～５５°であるグラウト材料である。【選択図】なし
