Abstract

In this study, 3D-printable fiber-reinforced cementitious composites with PE fiber contents of 0.75% were characterized. Specimens were extracted from 3D-printed elements and subjected to compression, splitting tensile, and bending tests to evaluate the mechanical characteristics of the printed elements. The results of the compression tests showed that the compressive strength of the specimens cored in the vertical direction was 109 MPa and the coefficients of variation ofthe compressive strength andYoung’s moduluswere smaller than those of the mold-cast specimens. Splitting tensile tests were conducted on specimens in which the direction of the interface between each printed layer (layer-to-layer interface) and the direction of crack propagation matched, and the result showed that, at 3.50 MPa, the cracking strength was 30% lower than that of the specimens whose direction of the layer-to-layer interface and crack interface did not match.
