Ein neues Material zur Verstärkung von Bauwerken

Memory Steel

(PresseBox) (Dübendorf, )
Ein neues, an der Empa entwickeltes Baumaterial steht kurz vor der Markteinführung: Mit «memory-steel» lassen sich nicht nur neue, sondern auch bestehende Betonstrukturen verstärken. Erhitzt man das Material (einmalig), spannt es sich wie von selber vor. Das Empa-Spin-off re-fer AG präsentiert das Material mit Formgedächtnis nun in einer Vortragsreihe.

Bislang wurden die Stahl-Armierungen in Betonbauwerken meist hydraulisch vorgespannt. Dazu sind Hüllrohre für die Führung der Spannkabel, Anker zur Kraftübertragung und ölgefüllte Hydraulikpressen notwendig. Der Raumbedarf all dieser Apparaturen schuf die geometrischen Rahmenbedingungen für jedes Bauwerk aus Spannbeton; die nachträgliche Versteifung älterer Bauten scheitert daher bisweilen am hohen Platzbedarf dieser bewährten Fqndwmo.
