Sticky rice–lime mortar is one of the most important technological inventions in the Chinese architectural history. In this work, an experimental study on the application of sticky rice–lime mortar in conservation of the stone tower in the Xiangji Temple was performed by means of the property characterization, SEM, XRD and DSC-TG analysis. Our Results indicate that paper fiber is the most effective admixture to endure freezing–thawing cycles and increase the compressive strength of sticky rice–lime mortar, and the use of aluminum sulfate reduces the drying shrinkage values and increases the compressive strength because of the formation of ettringite in sticky rice–lime mortar. It is suggested that 6% aluminum sulfate or 3% paper fiber may be the appropriate admixture of sticky rice–lime mortar in conservation of cultural relics. Based on the results of laboratory experiment, the sticky rice–lime mortar with 3% paper fiber is selected as the grouting material for the conservation of the Xiangji Temple tower.
