CHEMICAL SOLUTION COMPOSITION AND COMPOSITION FOR GROUND INJECTION
To provide: a composition for ground injection that provides foam with excellent compressive strength and inhibits whitening of water when coming into contact with water; and a chemical solution composition with excellent storage stability for use in the preparation of such a composition for ground injection.SOLUTION: A chemical solution composition contains a polyol, an imidazole based catalyst, a trimerization catalyst, and a cross-linking agent, where the polyol includes a polyether polyol, and where the cross-linking agent includes at least one selected from primary and secondary amines. The number average molecular weight of the polyether polyol is preferably from 200 to 6000.SELECTED DRAWING: None
【課題】圧縮強度に優れた発泡体を与え、水と触れた際に水の白濁を抑制する地盤注入用組成物、及び、このような地盤注入用組成物の調製に用いられる、貯蔵安定性に優れる薬液組成物を提供する。【解決手段】薬液組成物は、ポリオール、イミダゾール系触媒、三量化触媒及び架橋剤を含有し、ポリオールがポリエーテルポリオールを含み、架橋剤が、１級アミン及び２級アミンから選ばれた少なくとも１種を含むことを特徴とする。ポリエーテルポリオールの数平均分子量は、好ましくは２００～６０００である。【選択図】なし
