Abstract
Current research focuses on the use of carbon (C) textiles as cathodic protection (CP) anodes. Carbon fibres are of particular interest due to their excellent mechanical properties. However, the influence of anodic polarisation on the durability of carbon anodes is still not sufficiently understood. In previous works, the durability of carbon anodes was examined by experimental investigations in saturated calcium hydroxide (Ca(OH)2) solution. In this work, various anodes (carbon textiles with different impregnations, as well as mixed-metal-oxide-coated titanium (Ti)) were investigated after embedding in mortar. The type of mortar as well as the environmental conditions were varied in order to represent diverse conditions. Potentiostatic polarisation was implemented for 8 months. Results of this work show that CP with impregnated carbon textiles is, at least under the investigated conditions, possible.
