3D printing of mortar with continuous fibres: Principle, properties and potential for application

Important developments in additive manufacturing with concrete have been achieved the past decades. Yet, printed components usually do not comply building standards or basic reliability principles, and are commonly used as load-bearing components. A gap between research practice exists despite several attempts, off-the-shelf commercial solutions for reinforcement of 3D structural seem always expected. This article presents an alternative (pending patent [1]) structures. technology inspired by composite industry is called Flow-Based Pultrusion (FBP). strict control rheological behavior cementitious matrix ensures routing impregnation continuous rovings thin fibres (glass, basalt, etc.) without any motorization. The resulting material, Anisotropic Concrete, homogeneously reinforced a single direction, provides new possibilities, may enhance strength ductility hardened material but also help to better handling fresh laces during deposition, permitting inclined cantilever paths. paper describes process, its constraints, first experimental achievements investigations about mechanical performances such material.
