Abstract
Abstract A protective covering is provided for a tensioned cable encircling a concrete tank. The covering is in the form of a tube having its opposite ends in a frame mounted on the tank. After the cable is prestressed, grout is poured into one end of the tube to fill the annular space between the cable and tube for protection of the stressed cable against corrosion and vandalism.
