Abstract：To determine the ingredient ratio of rammed earth in Jiaoshan ancient emplacement （JAE） and improve its manufacture craft,the rammed earth sample was made by using the traditional method. Based on X-ray diffraction and scanning electron microscopy（SEM）,ancient rammed earth and modern rammed earth were compared on composition,and the ingredient ratio of JAE was determined by a comprehensive analysis. Mechanical properties of rammed earth sample were tested,and its stress-strain curves were obtained. The results show that the ingredient ratio of JAE＇s main materials,i.e. earth,lime and fine sand,is 4∶3∶3,and mechanical properties of JAE＇s rammed earth is similar to those of concrete. The constitutive relations of this rammed earth can be well fitted by improved Saenz formula. The results provide reference for maintenance of similar historic buildings.
