Abstract
The main idea of this contribution is to replace typical steel structures for heliostats by means of concrete due to its low costs. With respect to accuracy demands, a high-performance concrete is used that possesses high compressive and tensile strengths. The collector is designed as a strut-like structure with main radial beams and a central mount to ensure high stiffness. The design exhibits a circular shape to reduce shading. For construction, the concrete collector is dissolved into equal modules derived from symmetry reduction methods enabling a serial production. The modules are subsequently post-tensioned to form a heliostat. To show the feasibility, a small-scale prototype with a diameter of 3.2 m and a mirror area of 8 m² is developed that will be built up and qualified at the solar power tower Jülich, Germany. It consists of 4 modules and exhibits a weight of 744 kg.
