CEMENT COMPOSITION AND CAVITY FILLING MATERIAL
PROBLEM TO BE SOLVED: To provide a cement composition which is applied easily, has excellent packing property, keeps stably swelling properties for a long period of time even after prepared and is capable of suppressing material separation, and to provide a cavity filling material which can hold stable properties and states of even a cavity of a wet state and can suppress generation of a gap after filled in the cavity.SOLUTION: The powdery cement composition contains 100 mass of cement, 10-50 mass of a clay mineral containing smectite as an effective component, and one or more selected from carbonate, bicarbonate and phosphate of an alkali metal.
【課題】施工が容易なセメント組成物であって、良好な充填性を具備し、製造後も長期間安定した膨潤性を維持し、材料分離を抑制できるセメント組成物及び湿潤状態の空洞でも安定した性状を保持でき、充填空洞への充填後に隙間が発生するのを抑制した空洞充填材の提供。【解決手段】セメント１００質量に対してスメクタイトを有効成分とする粘土鉱物１０〜５０質量と、アルカリ金属の炭酸塩、炭酸水素塩及び燐酸塩から選ばれる１種又は２種以上とを含有する粉末状セメント組成物。【選択図】なし
