Abstract

The effects of grouting pressure, moisture content and temperature on the adsorbing capacity of epoxy resin grouting agent on the surface of silica sand were researched using a sand-packed model. Test results showed that the adsorbing capacity of epoxy resin grouting agent on the surface of silica increased with the increasing of grouting pressure when the pressure was under 0.7 MPa but decreased when the pressure was over 0.8 MPa. Adsorbing capacity of epoxy resin grouting agent decreased with raising moisture content of silica sand due to competitive adsorption between epoxy resin molecule and water molecule. Adsorbing capacity of epoxy resin grouting agent reduced sharply with raising temperature attributing to the influence of molecular activity and viscosity. Results of the study provided a reference for the control of grouting pressure and temperature and also for the modification of epoxy resin grouting agent.
