Sweden: Researchers at Chalmers University of Technology, Sweden, have developed a method to simplify the construction of textile-reinforced concrete structures, a move that is expected to lead to more environmentally friendly infrastructure like bridges, tunnels, and buildings. The new technique addresses the high carbon footprint of cement.
This innovation, involving carbon fibre textiles as a replacement for steel reinforcement, enables lighter structures with reduced cement usage, thereby lowering the overall carbon impact. Karin Lundgren, Professor of Concrete Structures at Chalmers Department of Architecture said "A great deal of the concrete we use today has the function to act as a protective layer to prevent the steel reinforcement from corroding. If we can use textile reinforcement instead, we can reduce cement consumption and also use less concrete, thus reducing the climate impact."
The research is detailed in a paper titled 'Textile reinforced concrete members subjected to tension, bending, and in-plane loads: Experimental study and numerical analyses', which was published in the Construction and Building Materials journal. The study, a collaborative effort between Chalmers University and Gdansk University of Technology in Poland, is supported by the Swedish Research Council.
