Effects of Polypropylene Fibers on the Mechanical Performance of a 3D Printable Mix

Abstract

Application of automation in construction work has now become need of the hour. Automation in construction work can be done by implementing a technique known as additive manufacturing technique. Use of additive manufacturing in construction sector has the potential to bring fourth industrial revolution by using 3D concrete printers. This paper is based ona parametric experimental study to evaluate the effect of Polypropylene (PP) fibers on mechanical properties of a 3D printable concrete. PP fibers were used invarying percentage ratio of 0.02, 0.04, 0.08, 0.12 and 0.16 of binder at constant W/B ratio.
