Geopolymers as inorganic binder in 3D printing application in construction
May 27-June 1, 2018
Digital fabrication and more specifically, 3D printing allows the production of very complex shapes with no extra cost for complexity and customization. This mass customization revolution opens new possibilities for the construction industry . For instance, structural elements can be designed with the exact amount of materials positioned in the right place. Recently 3D printing has been used to produce a formwork for high performance fiber reinforced concrete , which would reduce the environmental impact of the structure, by one third. However, this large scale binder-jet technology with organic binders (phenolic and furanic resins) causes serious problems for the indoor environmental quality of buildings through the release of volatile organic compounds when they are used as building structure.
