Abstract: Discontinuous fiber reinforced Engineered Cement-based Composites prepared by extrusion molding introduce advantages in cement product processing. Extrusion is a plastic-forming method whereby several structural shapes can be manufactured. Extrusion molding of cement products entails their formation under high shear and compressive forces. This leads to performance-enhancing densification of the material, while it also has the potential of producing products of superior geometrical tolerance and has a beneficial influence on the fiber orientation. There is evidence that short fibers are aligned by extrusion, leading to significantly improved mechanical properties of the material. Fiber alignment manifests in the main direction of the extrusion mechanism. Consequently, the mechanical properties of the fiber composite are improved in that direction.The aim of this paper is to substantiate the effectiveness of extrusion with respect to fiber orientation and interfacial bonding, hence forth leading to enhanced mechanical properties.
