COLD RESISTANT INORGANIC ANCHOR MATERIAL AND FIXING METHOD OF ANCHOR MEMBER USING THE ANCHOR MATERIAL
To provide a cold resistant inorganic anchor material that can secure a proper usable life even an environment below a freezing point, has excellent workability with little sagging property, is excellent in adhesiveness with an anchor member and can suitably maintain the strength, and a fixing method of the anchor material using the anchor material.SOLUTION: A cold resistant inorganic anchoring material contains ultrafast hardening binder and nitrite, and contains 10 to 50 mass% of CA and 3 to 40 mass% of C2AS as an ultra fast hardening mineral in the ultrafast hardening binder, and C12A7 is not substantially contained, nitrite is contained in the range of 3 to 13 mass% relative to 100 pts.mass of the ultrafast hardening binder.SELECTED DRAWING: None
【課題】氷点下の環境でも適切な可使時間を確保でき、ダレ性が少ない良好な施工性能を有するとともに、アンカー部材との付着性能に優れ、強度を良好に維持することができる耐寒用無機系アンカー材料及び当該アンカー材料を用いたアンカー部材の固定方法を提供する。【解決手段】耐寒性無機系アンカー材料は、超速硬性バインダー及び亜硝酸塩を含み、前記超速硬性バインダー中に超速硬性鉱物としてのＣＡを１０〜５０質量％及びＣ２ＡＳを３〜４０質量％含み、Ｃ１２Ａ７は実質的に含有せず、亜硝酸塩は、超速硬性バインダー１００質量部に対して３〜１３質量部で含有される。【選択図】 なし
