Cyber-Physical Fabrication of Functionally Graded Concrete

Research Project 2 (RP 2)

CYBER-PHYSICAL FABRICATION OF FUNCTIONALLY GRADED CONCRETE COMPONENTS FOR MULTI-STOREY BUILDINGS

The project concerns the development of a fabrication platform for functionally graded concrete components developed in Research Project 1 that are optimized towards resource efficiency with regard to loadbearing capacity under consideration of requirements specific to multi-storey buildings.

Based on the requirements on geometrical, mechanical, building physics requirements from Research Project 1, the work will focus on the conceptualization of the overall design-to-production process chain, definition of production processes for internal gradients, joints, external formwork as well as casting and assembly systems. The process integrates digital implementations of methods for design and optimization with physical processes - such as finely tuned mixing of high-performance concrete and its precise extrusion - as well as digital methods for process planning and control.

The overall requirement is to minimize the weight of components, extend the possibilities of fabrication to on-site application, and minimize the environmental impact of their manufacture in order to meet today's social and ecological challenges and to ensure the creation of an environment worth living in for future generations.

The project will be conducted in tight cooperation with co-design of functionally graded concrete building system, onsite cyber-physical construction platforms and robotic platform for cyber-physical assembly as well as holistic quality model.
