Abstract: A new type of 3-furyl-2-hexyl-acrolein (FHA) with high boiling point and low volatility was synthesized and used as diluent in epoxy grouting material. Effects of diluent ratio, diluent, curing agent, and accelerator on properties of epoxy resin grouting material were studied to get the optimum recipe. Diluent ratio of 2:1 to 1:1, diluent addictive amount of 20 % to 30 %, curing agent of 8.16 % to 11.76 %, and accelerator of 0.2 % to 0.4 % were selected to make the optimum physical and mechanical properties of epoxy grouting material. It was shown that this environmentally-friendly epoxy grouting material with comprehensive properties could replace the toxic and volatile furfural in the epoxy grouting material.
