Abstract:

On the basis of the grouting reinforcement of alkaline earth, the main performance parameters and properties of material under hydrostatic condition were studied in the laboratory. Based on the engineering requirement, the congealing time of material under different formulation were tested, the strength of net paste stone and rock soil body were tested by mechanical property test. Based on the material of reinforcement requirement, the durability and stability under different hydrostatic conditions were tested and compared with other materials. According to the performance parameters of grouting material and the characteristics of muddy fracture zone in Zhangmatun Iron, grouting material application method and effect were discussed systematically. The results showed that the congealing time of material could be adjusted precisely, the strength of net paste stone and rock soil body were higher, and the durability and stability were better.

Key words: grouting material, congealing time, age strength, durability, stability, grouting reinforcement
