| Abstract: | In order to solve the sand plup transportation difficulties, easy segregation, low rate of stone caking, and poor water plugging effect with the high density tail plup under the condition of karst dynamic water grouting, A new type of grouting materials named foam tail mortar has been prepared by experimental study. The material advantages include with strong anti-scouring ability, short initial setting time, high rate of stone caking, great compressive strength, stable performance, good adaptability, etc. The best matching parameters of foam tail mortar has been optimized and selected is suitable for grouting under the condition of karst dynamic water. |
