EXPERIMENTAL ANALYSIS OF ALLYLAMIDE GROUTING MATERIAL WITH TRIETHALKYLOL REDUCING AGENT AND ITS APPLICATION IN WAAL-BACK GROUTING

The MG-646 allylamid grouting materlal is widely using in China. But the β-dimethyl nitrileas reducing agent in the MG-646 is expensive and difficult available from market. For this reason,the Research Group for Grouting of Northeastern University tries to use triethalkylol to replace the β-dimethyl nitrile. The Research Group had done a field commercial trial in shaftwall grouting engineering at BalianchengCoal Mine,Jilin Province. This paper presents and analyses the successful results.
