1. A sheath for a structural cable of a construction work, the sheath having an outer surface to be exposed to an environment of the construction work,
wherein the outer surface of the sheath has a roughness texture to promote retention of frozen water, and wherein, in at least an upper part of the length of the sheath, the roughness texture covers more than half of the outer surface of the sheath,
wherein the sheath comprises at least two helical ribs forming protrusions and extending along respective helical paths in opposite directions along the outer surface of the sheath, the roughness texture being located between the protrusions.
