There are still many earthen ruins in the Northwestern China. Various kinds of damage, including fissuring, undercutting, caves, gullies and collapse, are great threats to the ruins. This paper focuses on the successful application of the PS-(C+F) materials and diverse grouting materials. The suitability of SH-(C+F) as a slurry grouting material was tested. The mechanical properties, hydrological properties, frost resistance, aging resistance of two indoor materials were compared.Also the effect of consolidation of cracks on the site was recorded. The results show that both SH-(C+F) slurry and PS-(C+F) have the same mechanical properties, but the former is slightly better for resistance due to permeability,disintegration, frost and aging. Therefore,SH-(C+F) is suitable as a slurry grouting material to reinforce fissured earthen sites. These results have important reference and guidance values for selecting reinforcing materials for fissured earthen sites in Northwestern China.
