| summary |
This ongoing research explores the opportunities of Polyvinyl Alcohol (PVA) as a reusable water-soluble 3D printed formwork for more circular and complex concrete casting. The paper first explores the feasibility of reusing PVA by discussing the various methods of expediting its dissolution process, harvesting, and dehydrating the material for recycling. Next, a fabrication case study of a partial vault structure is introduced to explore the added structural complexity and material optimization enabled by the water-soluble 3D printed formwork and finite element analysis methods. A series of block designs were tested with an Instron 5566 Universal Testing Machine with a 10 kN load cell. The compression testing demonstrated that the integration of reinforcement and certain design choices were effective. The results point to future research that may reduce the embodied carbon emissions of concrete casting through formwork recycling and material optimization. |
