Effect of Alkali-Resistant Glass Fiber Content on Performance of 3D Printed Mortar

Abstract

Abstract: As an excellent inorganic nonmetallic fiber material, alkali-resistant glass fiber (ARGF) has a good research value and the application potential in the field of civil engineering. As an emerging technology, 3D printing technology has high matching degree and application prospect in civil engineering. In this study, by adding varied ARGF fiber content and adjusting superplasticizer dosages, a series of 3D printed mortar (3DPM) with good printing performance were made, and the effects of ARGF fiber content on the mechanical properties were explored. The results show that, to achieve good printing performance, the flow spread in jump table test was suggested to be ranging from 180 mm to 220 mm. With the increase of fiber content, the flexural strength of 3DPM significantly increaseds, and the increases rate up to 99.2%. With the increase of fiber content, the compressive strength of 3DPM first increases and then decreases, and the optimum fiber mass content is 0.25%.

Key words: alkali-resistant glass fiber, 3D printing, printing property, flexural strength, compressive strength
