More than 8000 grottoes and cliff statues located in Sichuan and Chongqing area,most of them were made from sandstone.The properties of sandstone showed deteriorations due to long-term environmental effect,which posed threats to cultural relics.Basalt fiber (BF) and polyvinyl alcohol fiber (PVAF) were used instead of hemp to study the influence of fiber types and content on the traditional materials for conservation.The results showed that the addition of BF and PVAF can improve the flexural strength,tensile strength and volume stability,but had little effect on the compressive strength and composition of products.When the content of BF and PVAF increased,the dispersion of the fibers and the friction resistance decreased.The reinforcement effect of BF was more significant than that of PVAF at the same content.
