Effect of Nano-Silica on Structural Deformation, Rheological and Mechanical Properties of 3D Printed White Portland Cement-Based Materials

Abstract

Abstract: Compared with the traditional building materials, the printed structure build-up of 3D printed building materials proposes higher requirements on the rheological properties. The nano-silica was introduced to control the rheological properties of 3D printed white Portland cement-based materials, aiming to stabilize the paste structure and improve the mechanical properties. The experimental results show that the nano-silica shortens the setting time significantly, and improves the early mechanical properties of 3D printed white Portland cement-based materials. Meanwhile, the addition of nano-silica in 3D printed white Portland cement-based materials improves the yield stress and elastic modulus, which is conducive to resist its own gravity and reduce printed structural deformation. In addition, the 3 d compressive strength and flexural strength reach up to 46.9 MPa and 6.1 MPa, respectively, when the dosage of nano-silica reaches 0.5% (mass fraction). Based on the correlation of multiple rheological parameters, the dynamic yield behaviors present little influence on the deformation of the 3D printed structure, while the static yield stress presents the reverse phenomenon, which influences the structural deformation obviously. In conclusion, the introduction of nano-silica into the 3D printed white Portland cement-based materials can well control the rheological properties, and improve the printed structures and early mechanical properties.

Key words: white Portland cement, nano-silica, 3D printing, rheological property, mechanical property, setting time, structural deformation
