The Technology of Graded Concrete (2016-12)¶

In accordance with the principle of form follows force, the DFG Priority Program (SPP) 1542 - Lightweight Construction with Concrete - focuses on the provision of structural elements that are suitable for the stresses they are subjected to and that conserve resources. In view of the defined external shape of components such as ceilings, walls and columns, this concept must be systematically extended to include the targeted design of the internal structure of the components in addition to the adaptation of the external shape to the load situation. The technology of gradient concrete offers the possibility of aligning the internal structure of concrete components to the existing static loads and/or the physical load profile of the building. The high demands of gradient concrete technology require a holistic approach from mix development and component design to the automated production of the components. By combining the different areas of expertise of the Institutes for Lightweight Structures Design and Construction (ILEK), Materials in Civil Engineering (IWB) and System Dynamics (ISYS) at the University of Stuttgart, a complete process chain for the production of functionally graded concrete components could be realized. As a result, weight-reduced, energy-minimized and fully recyclable concrete components can be designed and manufactured.
