HYDRAULIC COMPOSITION FOR USE IN DRY SPRAY CONSTRUCTION METHOD
To provide a hydraulic composition for use in a dry spray construction method, applicable to forming a wall structure which is subjected to a load, developing high strength of not lower than 100 N/mmat a mid to long term material age of 28 days, exhibiting excellent adhesion at a time of spraying, and excellent in construction workability.SOLUTION: The hydraulic composition for use in a dry spray construction method, comprises (a) 100 mass parts of portland cement, (b) 7.5 to 26 mass parts in total of (b1) metakaolin and (b2) gypsum in a mass ratio (b1/b2) therein of 0.5 to 2.0, or (b3) 8 to 14 mass parts of silica fume, (c) 3 to 70 mass parts of water-absorptive porous fine aggregate of a water content of 12 to 25%, and (d) 50 to 145 mass parts of non-porous common fine aggregate of a water absorption ratio of not higher than 0.2%.SELECTED DRAWING: None
【課題】荷重負荷のかかる壁体構造物の形成にも適用可能な中長期の材齢２８日で１００Ｎ／ｍｍ2以上の高強度発現性を具備し、また吹付時に良好な付着性が得られ、しかも施工作業性に優れる乾式吹付工法用の水硬性組成物の提供。【解決手段】（ａ）ポルトランドセメント１００質量部、（ｂ）（ｂ１）メタカオリン及び（ｂ２）石膏を含有質量比（ｂ１／ｂ２）０．５〜２．０で合計７．５〜２６質量部、又は（ｂ３）シリカフューム８〜１４質量部、（ｃ）含水率１２〜２５％の吸水性多孔質細骨材３〜７０質量部、及び（ｄ）吸水率０．２％以下の非多孔質普通細骨材５０〜１４５質量部を含有する乾式吹付工法用水硬性組成物。【選択図】なし
