In the paper the authors discuss methods of anticorrosion protection before tendon installation and details concerning grouting – protection applied after installation. The authors describe details concerning cement grout, grouting with waxes, as well the grouting procedure itself. Durability of prestressed concrete structures is highly dependent on proper tendon anti-corrosion protection. It can be noticed that nowadays grouting with waxes is more common than cement grout. Research is also being done concerning production strands made of stainless steel or a direct anti-corrosion protection of steel that is used for strand production.
