Textile reinforced concrete sandwich panels

The main reason for the thickness of a concrete sandwich element is the requirement for the protective concrete cover for the steel reinforcement. By changing the steel reinforcement to non-corrosive textile fibre net this requirement could be strongly reduced. Use of textile reinforced concrete (TRC) makes it possible to produce much thinner and slimmer concrete facades in the future without changing their mechanical properties. This article presents selected results from Tekocrete project (Formas-BIC) concerning pilot production, modelling and full-scale testing of new light weight sandwich elements reinforced with AR glass and carbon fibre nets
