ABSTRACT OF THE DISCLOSURE A prestressed grouted anchor has a portion of an axially extending prestressed tension member grouted in a receiving material while the remaining portion of the tension member extends from the grouted portion. The remaining portion is separated from the grouted portion at a selected breaking point by reducing the tensile strength of the tension member as the result of exposing it to the action of heat, such as developed in an exothermic chemical reaction. If the tension member is prestressed and the resulting elastic elongation is maintained during the heating action with the elongation being greater than the elongation required under the heating action for effecting the severing of the tension member, then with progressive heat the tensile strength of the tension member is reduced and the elastic elongation progressively changes to plastic elongation with the tension member finally severing automatically at the selected breaking point.
