Silicate material is one of the most typical materials used in both traditional and modern buildings. This paper presents a comparative analysis of two silicate materials (ginger nut and Aga soil) used in ancient Chinese buildings. The research suggests that ginger nut and Aga soil have similar chemical compositions and physical properties. After they are burned at a temperature of 700°C ~ 1400°C, they will have a dual characteristic of hydraulicity and non-hydraulicity. As the temperature rises, the non-hydraulic constituent increases at first and then decreases, while the hydraulic constituent is increasing regularly. Their chemical composition and characteristics are similar to those of the “hydraulic lime” in Europe, and the modified ginger nut and Aga soil can be used for repairing and reinforcing the stone, earthen, brick and ceramic relics.
