ラウト材に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slag-water glass-based grout material which is poured into the ground to consolidate the ground,
In particular, not only can the gelation time be long and can be easily adjusted, but it also has good penetrability, and it reliably gels even at low temperatures, has a large initial strength, and has excellent durability. Regarding

くなって実用上問題となることが多かった。2. Description of the Related Art Conventionally, a cement-water glass grout is known as a grout material which is poured into the ground to consolidate the ground, but this grout material cannot cure for a long time. However, even if it could be done, the strength was often reduced and there were many problems in practical use.
【０００３】また、スラグと水ガラスからなるグラウト
材も知られているが、これはスラグからのカルシウムの
溶出が液温に大きく左右されるため、ゲル化時間の調整
が困難であった。特に、冬季では使用する水温が低いた
め、ゲル化を確実に行うことが困難であった。Further, a grout material composed of slag and water glass is also known, but it is difficult to adjust the gelation time because the elution of calcium from the slag is greatly influenced by the liquid temperature. Especially in winter, the temperature of the water used was low, and it was difficult to ensure gelation.
【０００４】そこで、上述のスラグ−水ガラス系グラウ
ト材にゲル化促進剤として消石灰、セメント等を添加す

たり、ゲル化強度が小さくなったり等の問題を引き起
し、充分な目的を達成するには至らなかった。Therefore, it has been attempted to add slaked lime, cement or the like as a gelation accelerator to the above slag-water glass grout material, but the gelation time becomes too short or the gelling strength becomes small. It caused problems such as sickness and did not reach the full purpose.

【発明が解決しようとする課題】一般に、グラウト材は
ゲル化時間が長過ぎたり、確実にゲル化しない場合に
は、地盤注入の後、注入領域から逸脱してしまう。した
がって、地盤の状況および注入目的に応じてゲル化時間
を調整し得るグラウト材が望まれている。Generally, when the gelling time of the grout material is too long or the gelling does not occur reliably, the grout material deviates from the injection area after the ground injection. Therefore, there is a demand for a grout material capable of adjusting the gelation time depending on the condition of the ground and the purpose of injection.

ウト材として、特に、ゲル化時間の調整が容易であり、
かつ、ゲル化時間を長くしても確実にゲル化するグラウ
ト材の出現が望まれていた。Particularly, the grout using the ultrafine particle slag attaches great importance to the permeability, and it was necessary to adjust the gelation time for a long time. Therefore, as the slag-water glass-based grout material, it is particularly easy to adjust the gelling time,
Moreover, it has been desired to develop a grout material that surely gels even if the gelation time is extended.

た。The present inventors have found that in the slag-water glass grout material, the alkali metal aluminate acts as a gelling time adjusting agent, that is, it acts as a retarding agent when the liquid temperature is high, and When it was low, they found to act as an accelerator, and completed the present invention.

明を完成するに至った。In the slag-water glass grout, the strength of the cured product is delayed in winter. In this case, alkali may be leached from the cured product and the final strength may not be sufficiently reached. On the other hand, the present inventors, by using the alkali metal aluminate salt in combination with the slag-water glass-based grout material, early development of early strength even in winter, not only does not cause a problem in final strength, but also excavation It was found that the next step can be promptly started when there is the next step, and the present invention has been completed.

グラウト材を提供することにある。Therefore, the object of the present invention is not only to provide a long slag-water glass grout material with a long gelation time and to be easily adjusted, but also to have a good permeability and to be surely gelled even at a low temperature. It is an object of the present invention to provide a ground-consolidating grout material that has high strength and excellent durability and has improved the above-mentioned drawbacks of the known art.

That is, when slag and water glass are mixed, calcium is eluted from the slag by the alkali of the water glass and the water glass gels. When alkali metal aluminate salt is added to this, it reacts with calcium, but the reaction rate with calcium between water glass and alkali metal aluminate differs depending on the amount of alkali metal aluminate salt added and the liquid temperature. Therefore, it is considered that the alkali metal aluminate acts as a retarder or an accelerator.
