Composition for tunnel reinforcement grouting
The present invention relates to a composition for tunnel reinforcement grouting which comprises: a sealing material including cement, blast furnace slag powder, bentonite, and slaked lime; and a main injection material including cement, sodium carbonate, slaked lime, quicklime, and silica fume. According to the present invention, provided is a composition of a sealing material which improves the efficiency of preventing collapse of a pore wall hole and the backflow of the injection material, while not limiting the injection of the main injection material as the gelation progresses at the proper time.
