Sand-lime mortar can present a potential failure hazard primarily because it is water soluble. This characteristic means that when exposed to moisture, it can begin to break down and lose its structural integrity. If rain or water infiltrates masonry where this type of mortar is used, it can lead to deterioration of the bond between bricks or blocks, ultimately compromising the stability of the entire structure. In environments where moisture is prevalent, this solubility factor poses a significant risk to long-term durability and safety.

The other characteristics mentioned, such as brittleness, UV sensitivity, or acid solubility, do not directly relate to the risks involved in water exposure to the same extent as water solubility does. While those factors can influence the performance and longevity of building materials, the specific failure hazard associated with sand-lime mortar is predominantly linked to its reaction to water.
