Abstract: This article studied the influence on the strength of grouting through grouting liquid contraction and bonded interface(by adding a coupling agent KH560 to improve the bonding interface)by experiment, and then tested the results by regression and correlation analysis. The analysis results show that two factors on the grouting intensity play a significant influence.
Keywords: grouting intensity; grouting liquid contraction, bonding interface; chemical grouting; coupling agent; grouting quality
