Therecent rise of terrorist attacks has reinforced the need formitigation of damage caused by blast loading on unreinforced masonry\nwalls. The primary goal of the techniques is to prevent the loss of life while simultaneously preserving the integrity of the structure.\nThis paper presents a compilation of recently available literature on blast protection of unreinforced masonry walls. It seeks to\npresent the state of the art in this field, including mitigation techniques considered as well as testing methods selected. Fiber reinforced\npolymers and polyurea are the two dominant retrofitting techniques being assessed in the field.Other techniques include but\nare not limited to polyurethane, steel sheets, and aluminum foam. Since there is no widely implemented standard for blast loading\ntest procedures, direct comparisons between the efficiencies of themitigation techniques proposed are not always feasible.Although\nfragmentation is an indicator of the efficiency of retrofits, it is currently measured by subjective observation of postblast debris.
