CHEMICAL FOR NATURAL GROUND CONSOLIDATION
PROBLEM TO BE SOLVED: To provide a two-pack type chemical for natural ground consolidation consisting of a liquid A prepared by blending water glass and polyol and further adding water and a liquid B mainly containing polyisocyanate, further enhancing filling property by preventing cloudiness of the liquid A while achieving low viscosity thereof and excellent in long-term storage stability.SOLUTION: The chemical is prepared by containing water in a liquid A prepared by blending water glass and polyol and further adding water with a ratio of 180 to 250 pts.mass based on 100 pts.mass of the solid component in the water glass, and by adjusting water and polyol to a ratio of 100:7 to 100:35 by mass ratio and further adding a dispersant.SELECTED DRAWING: None
【課題】水ガラスとポリオールとを配合し、更に水を加えて調製されるＡ液と、ポリイソシアネートを必須成分とするＢ液とからなる二液型の地山固結用薬液において、かかるＡ液の低粘度化を図りつつ、その白濁化を防止して、充填性を更に向上させると共に、長期保存安定性にも優れた薬液を提供すること。【解決手段】水ガラスとポリオールとを配合し、更に水を加えて調製されるＡ液を、水ガラス中の固形成分の１００質量部に対して１８０〜２５０質量部の割合となるように水を含有せしめ、且つ水とポリオールとが、質量比で１００：７〜１００：３５の割合となるように調整すると共に、分散剤を更に添加して調製した。【選択図】なし
