Abstract
Epoxy resin chemical grouting agents are widely used in the treatment of weak foundations and concrete cracks, especially the ones in alpine areas, it is important for the epoxy resin grouting agents with excellent performance at low temperature. The main agent of epoxy resin was modified by micromolecule formulating method and then a sulfhydryl modified low temperature curing agent was prepared in this paper. The epoxy resin chemical grouting agents with good groutability and curing effect were prepared and suitable for low temperature. Then the properties of grouting agents with different compositions were studied at - 8℃. This kind of grouting agent would had a widely application in treatment with weak foundations and concrete cracks at the temperature below 0 ℃.
