Abstract
The present paper concerns the newly developed formwork method for fabrication of concrete parts which combines high precision of CNC processing technologies with potentials of frozen sand as formwork material. Sand has been identified as beneficial material for production of complex concrete structures due to its good formability in combination with its full reusability. For the production of formwork elements using CNC milling, the sand is mixed with water and frozen into a solid state to ensure precise processing and a long-lasting stability of formwork geometry. In addition to the description of production method, the production of two specimen of thin-walled spatial concrete parts is demonstrated and discussed.
