The properties such as surface hardness, compressive strength, freeze-thaw resistance and other properties of the prepared glutinous rice mortar were determined by mortar performance. The influence of the species of aggregate, the size of the particle and the amount of the aggregate on the properties of glutinous rice mortar are discussed and its action mechanism is explored by means of SEM and XRD. Results show that the addition of silica sand, river sand and brick grain improve the shrinkage and freeze-thaw resistance. Among the three aggregates, brick grain make the freeze-thaw resistance of sticky rice-lime mortar increased by 125% compared to blank sample. However, with increase of aggregate particle size and bone ash ratio, the compressive strength, freezing-thawing resistance and shrinkage of aggregates decreased. Therefore, for the protection practice of brick cultural relic, it is suggested that the brick grain is added as the aggregate, the grain size is controlled to be within 3 mm, and the aggregate to lime ratio below 2:1, which is the optimal way to improve the performance of glutinous rice mortar.
