To assess the properties of polymer mortars for seismic damaged ancient masonry to be bonded and strengthened by steel strips, such as fibre-reinforced mortar and acrylic-emulsion cement mortar, it is vital to conserve the cultural relics of ancient masonry pagodas. In this paper, the compressive strength, split strength, carbonation, and weatherability of the polymer mortars were obtained from mechanical tests and freeze-thaw cycling tests. By comparing corresponding parameters and analyzing internal microscopic structures from electron microscopy scanning photos, the reliability of the repair scheme on physico-mechanical properties of the polymer mortars has been evaluated, and some suggestions have been proposed.
