Composite for additive manufacturing including flax byproducts and quarry fines
Résumé
This study work focus on the development of self-standing insulating wall elements using 3D printing technology. Additive manufacturing is promising for the construction industry as it allows complex geometry exploration but also prevent the need for formwork as it is in the traditional building techniques. In this research work, flax and quarry fines with a clay-like behavior are integrated in the mix design to obtain environment-friendly wall elements. Short flax fibers and quarry fines are mixed along with a high-content blast furnace slag cement to obtain the structural part of the wall. Effects of flax fibers inclusion into the material are investigated through mechanical tests and plastic shrinkage. Hollows of the 3D printed elements are then filled with a foam made up with flax shives and quarry fines. Finally, a 3D printing test session is displayed.
