Abstract:By the laboratory experiments,main performance parameters and characteristics under dynamic water condition of a new type grouting material are studied. The initial/final setting time of the grouting material under different water-cement ratios,different volume ratios of slurry to admixture and different temperatures are tested. The stone rate(3 h) of material is tested. Based on the material and process requirements of dynamic water grouting engineering,slurry retention rate with different water velocities and the pumpability after initial setting time are tested. According to the performance parameters of grouting material and the field condition,the optimum mixture ratio of the new grouting material is determined. The operation technology of dynamic water grouting material is studied.
