Sandwich Panels with Thin-Walled Textile-Reinforced Concrete Facings

Textile-reinforced concrete (TRC) is a composite material made of open-meshed textile structures and a fine-grained concrete. The application of TRC leads to the design of filigree and lightweight concrete structures with high durability and high quality surfaces. In recent years, TRC has become an attractive choice for the production of ventilated façade systems. To attain the goal of a lightweight façade with large spans and without bracing stud-frame-systems, sandwich panels with two thin TRC-facings and a core of rigid polyurethane foam have been developed at RWTH Aachen University. Within a compact section, this slender building envelope provides a capable load-bearing behavior, superior heat insulation and fire resistance as well as a sufficient sound insulation. In the paper, the investigated production methods, the test results of sandwich members loaded by bending and shear forces, tests on sound insulation and fire resistance, as well as the deduced calculation models are presented.
