CHEMICAL LIQUID COMPOSITION FOR NATURAL GROUND CONSOLIDATION
To provide urethane-based chemical liquid for natural ground consolidation, excellent in reaction activity and causing less environment pollution, and to provide an urethane-based chemical liquid composition for natural ground consolidation, capable of forming a consolidated body having high strength and excellent flexibility, and high plasticity and fire retardancy, and not initiating problems such as white turbidness and foaming when contacting water such as water leakage and sump water.SOLUTION: A chemical liquid composition for natural ground consolidation comprises A liquid containing an active hydrogen group-containing compound and a catalyst as essential components, and B liquid containing polyisocyanate as the essential component. The A liquid contains at least an active hydrogen group-containing organic compound having a cyclic structure as the active hydrogen group-containing compound, and at least a carboxylic acid metal salt as the catalyst. The B liquid contains at least an aliphatic polyisocyanate compound as the polyisocyanate.SELECTED DRAWING: None
