Abstract:	Ein großer Teil der weltweit vorhandenen Silos ist über 50 Jahre alt und bedarf in den kommenden Jahren einer Erneuerung oder Sanierung. So war bei einem im Jahr 1962 erbauten Doppelkammersilo aus Spannbeton mit einem Fassungsvermögen von 20 000 t Zucker eine Rissinstandsetzung erforderlich. Im Rahmen einer Voruntersuchung wurde hierfür ein Vergleich möglicher Instandsetzungsverfahren durchgeführt. Im Ergebnis wurde die Verstärkung mit Textilbeton gewählt. Für die ca. 3 100 m2 große Sanierungsfläche wurden ca. 14 000 m2 textile Bewehrung sowie ca. 150 t Feinbeton verbaut. Crack repair of a sugar silo Worldwide, a great part of the existing silos is older than 50 years and require renovation in the coming years. For example, crack repair was necessary for a twin compartment silo, which is made of prestressed concrete and can hold up to 20 000 t of sugar, from 1962. In this context, a preliminary investigation was made with the aim of comparing the different possibilities for restoration. Eventually, strengthening through textile reinforced concrete was chosen. Approximately 14 000 m2 of textile reinforcement and 150 t of fine grained concrete were used for approximately 3 100 m2 restoration area.
