HIGH-STRENGTH GROUT COMPOSITION AND HIGH-STRENGTH GROUT MATERIAL
PROBLEM TO BE SOLVED: To provide a high-strength grout composition and a high strength-grout material which are easy to be kneaded and mixed, have a small dripping amount after filling while having high initial flowability after kneaded and mixed, and can obtain a high compressive strength.SOLUTION: A high-strength grout composition which contains a thickener that is not crosslinked with cement, an amorphous aluminosilicate mineral powder, gypsum, a water-reducing agent, and a hydroxyl group and has a viscosity of 2 mass% concentration of less than 1,000 mPa s, and a thickener that is crosslinked with a part of the hydroxyl group and has a viscosity of 2 mass% concentration at 20°C of 1,000-5,000 mPa s.SELECTED DRAWING: None
【課題】練混ぜがしやすく、練混ぜ後の初期の流動性が高いにも関わらず充填後の垂れる量が少なく、かつ高い圧縮強度が得られる高強度グラウト組成物および高強度グラウト材を提供。【解決手段】セメント、非晶質アルミノ珪酸鉱物粉末、石膏類、減水剤、水酸基が架橋されていない２質量％濃度の粘度が１０００ｍＰａ・ｓ未満の増粘剤および一部の水酸基が架橋された２０℃における２質量％濃度の粘度が１０００〜５０００ｍＰａ・ｓの増粘剤を含有する高強度グラウト組成物。【選択図】なし
