Steel-reinforced concrete has been a widely used material in the construction industry for over a century. However, steel’s metallic nature necessitates increased section thickness to prevent corrosion and leads to frequent repair or replacement especially in the infrastructures such as bridges. Additionally, shaping steel for curved structures is labor-intensive and costly, imposing practical limits on the geometries that can be achieved. A promising alternative is textile-reinforced concrete that is a non-corrosive composite due to non-metallic properties of the textiles. This novel technology enables the construction of longer-lasting structures and reduction in the concrete consumption. Moreover, its flexibility in shaping allows integration onto the curved surfaces. This study investigates the shaping of thermoplastic-coated textile reinforcement for curved structures through the construction process within the scope of a CORNET (Collective Research Networking) project. It presents a methodology, key know-how and considerations to successfully apply these reinforcement systems in free-form structures. A large-scale free-form prototype structure was utilized to evaluate the drapability of the textile reinforcement used in this study. In the experimental investigations, the textiles were heated to the glass transition temperature by infrared heater and then pressed on the formwork to conform the shape. The results indicated that thermoplastic coated textile reinforcement can be effectively shaped on large-scale formwork. The findings of this study demonstrate that thermoplastic-coated textile reinforcements offer a promising approach for reinforcing curved structures, paving the way for more durable, sustainable and cost-effective solutions in the construction industry.
