Design and Manufacture Process of Atypical Glass Fiber-reinforced High-strength Concrete Structural Product Using 3D Powder Binding Technique

Abstract

Concrete is an inorganic material composite in which coarse aggregate and fine aggregate are combined by hydration reaction of cement and water. It provides high fluidity and excellent workability before concrete is hardened. In order to have the desired shape, a special purpose mold is needed. The production of atypical concrete structures with complex structures can be printed out by 3D printing technology. The model used in this article has been successfully developed through 3D powder binding technique. In this article, the feasibility of atypical concrete table fabrication based on 3D printing are confirmed. Through experiments, discussion of mechanical properties of concrete materials. High-performance concrete with glass fiber added has a significant improvement in pressure resistance and bending resistance which that glass fibers as fiber reinforcement in ultra-high strength concrete was proved. Finite element simulation determines the force distribution and deformation analysis of atypical concrete table model in this study.
