THICKENING ADMIXTURE FOR SPRAYING AND SPRAY MATERIAL USING THE SAME
To provide a thickening admixture for spraying that reduces powder dust generated in spraying and improves initial strength development property, and a spray material using the same.SOLUTION: There is provided a thickening admixture for spraying composed of thickener and inorganic material, in which a Blaine specific surface area of the inorganic material is 4500 to 20000 cm/g, and a mass ratio ([mass of the inorganic material]/[mass of the thickener]) of the inorganic material to the thickener is 0.2 to 3.5. It is desirable that the inorganic material is gypsum and/or fly ash, and the thickener is a cellulose type thickener.SELECTED DRAWING: None
【課題】吹付時に発生する粉塵を低減し、且つ、初期強度発現性を向上させる吹付用増粘性混和剤及びそれを用いた吹付材料の提供。【解決手段】増粘剤及び無機材料からなる吹付用増粘性混和剤であって、無機材料のブレーン比表面積が４５００〜２００００ｃｍ２／ｇであり、増粘剤に対する無機材料の質量割合（［無機材料の質量］／［増粘剤の質量］）が０．２〜３．５である、吹付用増粘性混和剤。無機材料は、石膏類及び／またはフライアッシュが望ましく、増粘剤は、セルロース系増粘剤が望ましい。【選択図】なし
