RAPID HARDENING TYPE LIGHTWEIGHT GROUT COMPOSITION
PROBLEM TO BE SOLVED: To provide a rapid hardening type lightweight grout composition providing a lightweight grout material high in strength in material age of 3 hours and having rapid hardening property even with the chloride component in a lightweight grout material of 0.30 kg/mor less, having high flowability and sufficient usable life as a grout material and being lightweight with kneading completion unit volume mass of 1.6 kg/L or less.SOLUTION: There is provided a rapid hardening type lightweight grout composition containing (A) cement, (B) gypsum, (C) calcium aluminates containing CaO AlOof 50 mass% or more and having powder degree of 3500 to 5500 cm/g and (D) a lightweight aggregate having unit volume mass of 0.5 kg/L or less, with the (D) lightweight aggregate of 10 to 30 pts.mass based on total 100 pts.mass of the (A) cement, the (B) gypsum and the (C) calcium aluminates.SELECTED DRAWING: None
【課題】軽量グラウト材中の塩化物含有量が０．３０ｋｇ／ｍ３以下でありながら、材齢３時間における強度が高く速硬性であり、グラウト材としての高流動性及び充分な可使時間を備え、練り上がりの単位容積質量が１．６ｋｇ／Ｌ以下と軽量である軽量グラウト材が得られる速硬型軽量グラウト組成物を提供すること。【解決手段】（Ａ）セメント、（Ｂ）石膏、（Ｃ）ＣａＯ・Ａｌ２Ｏ３を５０質量％以上含有し、且つ粉末度３５００〜５５００ｃｍ２／ｇであるカルシウムアルミネート類及び（Ｄ）単位容積質量０．５ｋｇ／Ｌ以下の軽量骨材を含有し、（Ａ）セメント、（Ｂ）石膏及び（Ｃ）カルシウムアルミネート類の合計１００質量部に対し、（Ｄ）軽量骨材を１０〜３０質量部含有することを特徴とする速硬型軽量グラウト組成物。【選択図】なし
