From thousands of years of architectural practice in China,many creations with Chinese characteristics have been found,one of which is the traditional Chinese organic-inorganic mortar represented by the sticky rice-lime mortar.This article reviews the progress of relevant studies since 2007,including the followings:innovative progress of chemical detection and ELISA analytical technique on organic residuals from traditional mortar;test results and cause analysis of 1149 mortar samples from 252 ancient architectural sites in China;experimental verification of the curing mechanism of traditional cementing materials such as sticky rice-lime mortar and tung oil mortar;influences of the research achievement of sticky rice-lime mortar and its status in the history of world composite materials;recent new findings of organic additives in the Neolithic Age Baihuimian(white lime layer)and tracing of its relevant origin;study of the modified traditional sticky rice-lime mortar and its applications in cultural relics conservation projects;etc.The series of exploratory research not only provides materials and technologies for traditional architectural conservation,but also presents vivid cases for the promotion of Chinese civilization.
