Abstract: In order to prepare a sandstone stone cultural relic grouting material with adjustable properties and meet the requirements of multi-scene application, the four-angle experiment method was adopted. The hydraulic lime (NHL2), sulphoaluminate cement (SAC), metakaolin (MK) and water-based epoxy resin (WER) were used as raw materials to prepared grouting materials with different formulations. Furthermore, the mechanical properties, setting time, fluidity and abonding strength of the grouting material were tested and analyzed. The results indicate that the grouting material with higher content of NHL2 and MK is suitable for repairing murals or mosaic patterns because of its low compressive strength and bonding strength. The grouting material with higher content of SAC and WER has higher compressive strength and bonding strength, which is suitable for repairing cliff and overhanging sandstone stone relics. Besides, the grouting material with higher content of WER and MK has good toughness and deformation ability, and it is suitable for repairing sandstone cultural relics susceptible to external stress.

Key words: sandstone stone cultural relic, grouting material, four-angle experiment method, performance adjustment, multi-scene application
