Consolidation experiment on earthen architecture site in arid region

Combining the consolidation project of the Gaochang site in Xinjiang Uygur Autonomous Region, silicone-acrylic emulsion has been applied to the consolidation of the samples of the Gaochang site. Tests including chemical analysis, fused-salt analysis, penetration depth, gas permeability, resistance to salt erodibility, unconfined compressive strength, freeze-thaw cycles, wind erosion and analysis of X-ray are carried out. Experimental research reveals that the clay samples treated with the new material have an outstanding effect and can gain good stability against water decomposition, fused-salt, freeze-thaw cycle and wind erosion while the appearance and water permeability nearly keep unchanged. The compressive strength can be improved definitely, thus the soil surface has no incrustation to avoid the soil desquamate. Silicone-acrylic emulsion is an excellent anti-weathering consolidation for earthen architecture site protection in the arid regions of Northwest China.
