Abstract: In this paper, the ultimate load carrying capacity, strain and failure modes of the ultra-high performance mortar (UHPM) masonry columns were tested and analyzed and compared with the conventional mortar (CM) masonry columns. Two kinds of different masonry material, common sintered brick and concrete block, were used for constructing test specimens. The result shows that the compressive strength of UHPM masonry column be constructed of common sintered brick is about 1.75 times higher than CM masonry columns. For the col- umns constructed of concrete block, the compressive strength of UHPM masonry column is increased 2.01 times. Moreover, the skeleton texture formed by UHPM was still bearing loads when the block was destroyed and also restrained the horizontal deformation to improve the ductility of masonry column as well. Therefore, it is necessary to take the effect of skeleton into consideration when it comes to ultimate load-carrying capacity and deformation calcula- tion of the concrete UHPM short columns under axial loads.
