To provide an agent liquid composition capable of cutting off without drain even under a large amount of water leakage or sump water while maintaining easy input operation of an agent liquid, effectively inhibiting generation of white turbidness of water when contacted with water, and advantageously suppressing drain of the agent liquid.SOLUTION: In an agent liquid composition for grouting consisting of an A liquid mainly containing an active hydrogen group-containing compound and a B liquid mainly containing polyisocyanate, the active hydrogen group-containing compound contains a first active hydrogen group-containing compound consisting of a polyol compound having a hydroxyl group of 90 mass% or more, and further at least a second active hydrogen group-containing compound with higher reaction rate than the first active hydrogen group-containing compound.SELECTED DRAWING: None
【課題】薬液の容易な注入作業を確保しつつ、大量の漏水や湧水下でも流出せずに、止水することが出来、且つ水と触れた際の水の白濁の発生を効果的に防止せしめて、薬液の流出を有利に抑え得るようにした薬液組成物を提供する。【解決手段】活性水素基含有化合物を主成分とするＡ液と、ポリイソシアネートを主成分とするＢ液とからなる地盤注入用薬液組成物において、前記活性水素基含有化合物が、ヒドロキシル基を有するポリオール化合物からなる第一の活性水素基含有化合物を９０質量％以上の割合で含有し、更に、該第一の活性水素基含有化合物より反応速度の速い第二の活性水素基含有化合物を少なくとも含有するように構成した。【選択図】なし
