CAVITY FILLING MATERIAL AND CAVITY FILLING METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a cavity filling material having improved processability by good flowability and holding effect, further being environmental friendly by reducing elution of hexavalent chromium, and a cavity filling method.SOLUTION: There are provided (1) a cavity filling material containing cement, calcium sulfite having pH of 9 or more, oxidation reduction potential (ORP) of 50 mv or less and MgO content of 0.5% or more and water, and the calcium sulfite of 0.05 to 2 pts.mass based on 100 pts.mass of the cement, (2) a cavity filling material according to (1), further containing one or more plasticization material selected from a group of silicates, sulfates, alkali thickening emulsions, and cement minerals, and (3) a cavity filling method including filling a cavity with the cavity filling material according to (1) or (2).SELECTED DRAWING: None
【課題】良好な流動性と保持効果で施工性が改善し、そのうえ、六価クロムの溶出を低減することで、環境に配慮した空洞充填材料、及び空洞充填工法を提供する。【解決手段】（１）セメントとｐＨ９以上で酸化還元電位（ＯＲＰ）が５０ｍｖ以下のＭｇＯ含有量が０．５％以上である亜硫酸カルシウムと水を含有してなり、セメント１００質量部に対して亜硫酸カルシウムを０.０５〜２質量部である空洞充填材料、（２）さらに、ケイ酸塩類、硫酸塩類、アルカリ増粘エマルジョン類、セメント鉱物類の群の中から選ばれる１種又は２種の可塑化材を含有してなる（１）の空洞充填材料、（３）（１）又は（２）の空洞充填材料を空洞に充填してなる空洞充填工法、である。【選択図】なし
