Deliberate Deformation of Concrete in the Fresh State: Crack Risk and Efficient Production of Curved Precast Elements

The production of double-curved precast concrete elements for cladding or shell structures requires expensive CNC (computer numerical control)-milled formwork. As an alternative method, the innovative flexible mould for economically efficient and sustainable production of such elements is discussed in this paper. This method comprises the use of...

Assessment of concrete characteristics during the deliberate deformation of a flexible mould after casting

Expensive CNC (computer numerical controlled)-milled formwork is required for the production of double-curved precast concrete elements for cladding or shell structures. The innovative flexible mould method for economically efficient and sustainable production of such elements, developed at Delft University of Technology, comprises the use of a...

Crack Evaluation in Double-Curved Concrete Elements

A new architectural concept is being developed nowadays - free-form design, which allows the architects to add personality to a building through the shape itself. To sustain this development, the existing and available production techniques have to be combined with new technological innovations. The flexible mould system uses the traditional...
