Concrete Fabrication by Digitally Controlled Injection
This paper explores the volumetric modification of material properties through precise injection of chemical agents as a new method of concrete fabrication. We inject concrete while in its slurry state with a hydrated aluminium solution, triggering an effervescent reaction. This reaction causes changes in material density which affect the structural integrity and visual characteristics of the end-product once it is set. The process is administered by a purpose-built end-effector attached to an industrial robotic system and guided by a parametric design system. Being able to produce localized differentiation, suggests for an innovative approach to a fabrication technique of texturing, 2D and 3D forming of concrete.
