Effect of TiO₂ Nanoparticles on the Fresh Performance of 3D-Printed Cementitious Materials.

ABSTRACT: 3D printing (3DP) of cementitious materials shows several advantages compared to conventional construction methods, but it requires specific fresh-state properties. Nanomaterials have been used in cement-based materials to achieve specific fresh and hardened properties, being potential candidates for 3DP applications. However, there are no reports on using TiO₂ nanoparticles (nano-TiO₂) in 3DP cementitious composites. Thus, the current work aims to assess the effect of nano-TiO₂ on the fresh performance of 3DP cementitious materials. For this purpose, nano-TiO₂ was incorporated in pastes and mortars from 0 to 1.5 wt.%. Time-resolved hydration (in situ XRD) and rheological and printing-related properties (buildability and printability) were evalua
