A modifiable and optimized structural system for circular use of buildings made of precast concrete

Concrete is a widely used material in the building industry. In Denmark, precast concrete elements are commonly used for building structures. The tradition of precast concrete structures started in the 1950s, when industrialization and standardization of production methods were prominent. Since then, the production and construction of precast concrete structures for buildings has developed into an efficient industry with a skilled labor force and a wealth of accumulated knowledge. Furthermore, concrete has some beneficial material properties and performs well within technical requirements like durability, acoustic insulation, fire safety, and heat accumulation. For those reasons, concrete is often chosen as a material for structures in the tradition-driven construction industry.
