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 technologies for pre-cast concrete fabrication to realize curved concrete elements. The flexible mould system relies on deformation of the concrete panels at very early age, when the tensile strength of the material has just started to develop and has not reached high values yet. Due to this physical deformation and the forced strains thus created in the material, a crack pattern can be formed on the surface of the element. The current research provides a quantitative and qualitative analysis of the cracks formed due to physical deformation. A range of influencing parameters were considered in the research: deformation time, radius of deformation, thickness of the elements and water/cement ratios. Also two alternative materials were analyzed and evaluated as potential replacements for the traditional concrete mixture. The results of the current research showed that fabrication of double-curved elements by using a flexible mould system can be realized without affecting considerably the concrete’s microscopic structure. A list of recommendations is provided as a result of the current thesis for the parties which in the future will be potentially involved in designing and manufacturing double-curved concrete elements. The double-curved concrete elements promise to bring a significant amount of flexibility in the next generation of architectural entities.
