Micro-cable reinforced geopolymer composite for extrusion-based 3D printing

Ma, Guowei, Li, Zhijian, Wang, Li, Bai, Gang·2019·Materials Letters

Abstract

Abstract Geopolymer has been applied to accommodate the rapid development of 3D printing in civil engineering practices and contributed this technique to reach its maximum eco-friendly potentials by eliminating the use of Portland cement. However, inherent problems with 3D printing concrete lie in the low tensile strength and poor ductility due to non-reinforcement, which greatly limit the application of 3D printing materials and structures. Hence, this study experimentally explores the feasibility of directly entraining a continuous micro steel cable (1.2 mm) during filaments (12 mm) deposition process, forming a reinforced geopolymer composite material. Three different printing path configurations are deigned to verify the applicability of micro-cable reinforced geopolymer composite for extrusion-based 3D printing. Flexural bending capacities of the proposed composite is measured and evaluated through four-point bending test. The results prove the well bonding and coordination of the micro-cable and geopolymer. Significant improvement of mechanical strength, toughness and post-cracking deformation of geopolymer composite are demonstrated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
