Collaborative research on carbon reinforced concrete structures in the CRC/TRR 280 project

Abstract

New materials allow new building designs and construction types. However, initial construction projects using the new materials show that traditional construction principles ‐ in the case of carbon reinforced concrete those derived from steel reinforced concrete ‐ are still being used. In other words, conventional materials are merely substituted. Only combined with intelligent construction strategies it is possible to exploit the full potential of innovative materials. Detached from established patterns of thought, the fundamentals for a new way of building with concrete are to be created in the frame of the Collaborative Research Centre Transregio (CRC/TRR) 280 project “Design Strategies for Material‐Minimised Carbon Reinforced Concrete Structures–Principles of a New Approach to Construction” at Technische Universität Dresden (TUD) and RWTH Aachen University. These are to be based on profound insights into the mechanical behavior of novel mineral structures. Innovative lightweight construction strategies and material composites reduce resource and energy consumption while maintaining high levels of usability, structural safety, and durability, while the aspirational esthetics make a valuable contribution to the culture of building. The long‐term research alliance of TUD and RWTH pools the excellent competencies, inspiring research into material‐minimized construction with mineral composites. The article highlights the research activities planned for the first period from July 2020 to June 2024.

Distributed strain measurements in thin expansive concrete slabs with biaxial textile reinforcement

“…Thus, for expansive concrete with carbon textile reinforcement another standard procedure is needed. The currently ongoing research project, “Chemical prestressing of folded and shell‐type carbon‐concrete structures” within the Collaborative Research Centre/Transregio 280 “Design Strategies for Material‐Minimised Carbon Reinforced Concrete Structures—Principles of a New Approach to Construction,” 25 aims to propose such a method.…”

Development of a method and technology for the production of 3D knitted reinforcement grids

“…Sustainability here means above all increasing energy and resource efficiency. Fibre-reinforced plastic composites (FRP), for example, for textile construction [1,2] or injection moulding applications [3,4], have great potential for the implementation of resource-saving and energy-efficient lightweight construction solutions due to the diverse possibilities of adapting their properties to the application requirements. With such solutions, advantages can be achieved, especially for components with complex geometry, if it is possible to reduce the previously high manufacturing costs of preforming with several, partly manual process steps and/or manufacturing steps [5,6].…”

Advanced Carbon Reinforced Concrete Technologies for Façade Elements of Nearly Zero-Energy Buildings

“…Frenzel et al provide detailed information about the design, production, and assembling processes [6]. Further collaborative research on carbon reinforced concrete structures is currently being carried out in a Transregio project (TRR 280), focussing on further structural optimization [7].…”
