HYDRAULIC COMPOSITION AND ANCHOR FIXATION CAPSULE USING SAME
PROBLEM TO BE SOLVED: To provide a hydraulic composition having: a rapid hardening property of being able to be hardened rapidly even when placed by using cold water and at cold temperature; a high-early-strength property of being able to develop high strength in the initial stage of its placement; capability of maintaining high strength for a prolonged period; capability of securely filling the inside of a drilled hole because of its excellent fluidity on installation; and excellent workability of being able to insert an anchor bolt without using equipment: and an anchor fixation capsule using the same.SOLUTION: The hydraulic composition is a hydraulic composition for a cold district, capable of hardening by contacting with water at a working temperature and/or a peripheral temperature of 10°C at the highest, and contains a hydraulic component containing Portland cement, aluminous cement, and a quick setting admixture; a strength enhancer containing kaolin as the main component; a fluidization agent; and a setting modifier.SELECTED DRAWING: Figure 1
【課題】冷水を用いて低温下で打設しても速やかに硬化する速硬性と、打設初期に高い強度を発現する早強性とを有し、さらに長期にわたって高強度を維持できるとともに、施工時に流動性に富んでいることにより、確実に削孔内を充填でき、機材不要でアンカーボルトを挿入できるという施工性に優れる水硬性組成物、及びこれを用いたアンカー定着カプセルを提供する。【解決手段】水硬性組成物は、水との接触により最高で１０℃の作業温度及び／又は周辺温度で硬化する寒冷地用の水硬性組成物であって、ポルトランドセメント、アルミナセメント、及び急結剤を含有する水硬成分と、カオリンを主成分とする強度増進剤と、流動化剤と、凝結調整剤とを含むものである。【選択図】図１
