• Provide protection to the prestressing steel against corrosion; • Provide a bond between the prestressing steel and the ducts where required for the design of the structure; • Allow transfer of compressive stresses in the structure in a direction transverse to internal tendons; • Fill all voids where water may accumulate and cause frost damage. The testing regimes anticipated by this European Standard include three levels: (1) Initial type and audit testing in accordance with this European standard; (2) Suitability testing for confirmation of the selected grout for a specific project in accordance with EN 446; (3) Inspection during grouting works on a specific project in accordance with EN 446. The test methods for each of the regimes are given in EN 445.
