QUICK HARDENING BURYING MATERIAL
PROBLEM TO BE SOLVED: To provide a burying material which has high water content and such a flowability that it can be easily and uniformly filled even into details of a burying part in a short period of time and, which hardens in a short period of time when buried or backfilled and which has strength development suitable for re-excavation after backfilled.SOLUTION: There is provided the quick hardening burying material which contains: 100 pts.mass of cement; 15 to 75 pts.mass of calcium aluminum having a molar ratio of CaO and AlO, CaO/AlO=1.2 to 1.6; 750 to 1500 pts.mass (in terms of solid component) of 1 or more kind selected from a group of sand, aggregate and construction sludge; 15 to 75 pts.mass of gypsums; and 2 to 7.5 pts.mass of a setting modifier and which has a water content of 600 to 1200 pts.mass.
【課題】 埋設箇所の細部まで短時間に満遍無く容易に充填できるような流動性を具備する高含水率の埋設材であって、埋設や埋戻しの際は短時間で硬化し、且つ埋戻し後の再掘削にも適した強度発現性を具備する埋設材を提供する。【解決手段】 セメント１００質量部、ＣａＯとＡｌ2Ｏ3の含有モル比がＣａＯ／Ａｌ2Ｏ3＝１．２〜１．６のカルシウムアルミネート１５〜７５質量部、土砂、骨材及び建設スラッジの群から選ばれる１種又は２種以上７５０〜１５００質量部（固型分換算）、石膏類１５〜７５質量部および凝結調整剤２〜７．５質量部を含有し、含水量が６００〜１２００質量部であることを特徴とする速硬性埋設材。【選択図】 なし
