| Abstract: | Grouting is a key technique for anti-seepage and reinforcement in the construction of civil engineering,water conservancy and mining engineering.Based on the research literatures concerning grouting techniques both at home and abroad,theoretical achievements of"percolation effect"and"time-space variability of viscosity"of the granular slurries like cement are summarized,application status and development prospect of new materials of nonaqueous reactive polymers and CW epoxy resin as well as microbial bacterial liquid are discussed,and the break through of numerical simulation on mesomechanics is introduced. |
