Abstract/Summary
This project is an exploration of cardboard as a potential material for construction formwork for concrete columns. Multiple material tests were conducted to explore the behavior of cardboard and concrete. Multiple specimens of cardboard were tested for modulus of elasticity, moment of inertia, and tensile strength. Concrete was tested for its apparent lateral fluid pressure under vibration. Cardboard formwork was then designed and constructed based on these tested behaviors. The final design of the formwork consisted of folding cardboard sheets lined with hardboard, supported by wood studs, and tied by plastic banding straps.
Ultimately, two concrete columns―8' and 10' in height―were constructed using the formwork. They were measured for their deviation from their intended 12"x12" cross-section, and the formwork was qualitatively assessed for its performance during and after the concrete pour.
