Abstract:Natural hydraulic lime is extensively applied to protection and restoration of historic building. Based on the studies of conventional natural hydraulic lime(Yangshao cement),we conducted experimental analysis of fundamental physical properties and environmental factors of calcinated Ginger nut and Aga soil,and compared to two European natural hydraulic limes(NHL2,NHL5). The results indicate that,Ginger nut and Aga soil burned calcinated at 1 000 ℃ for 3 hours had the similar characteristics to those of European water limes:less shrinking and deforming capacity,great interval porosity,good water and gas permeability,relatively stronger resistance to freeze thawing,stability in water,resistance to changes of temperature and humidity,and good resistance to erosion of alkaline medium;flexural strength and compressive strength of calculus body matched by materials of different ages tended to increase. The study results indicated that,after scientific modification,these two silicate materials applied to Chinese ancient buildings can be used in consolidation of historical relics made of stone and soil. The results have important significance on the spreading of traditional Chinese silicate materials.
