Application of Cellulose Nanomaterials in 3D Printed Sustainable Building Composites

Presented By: Mehdi Khanzadeh Moradllo, Temple University

Description: The potential for the building industry to adopt the use of 3D printed cementitious materials has been receiving increasing attention. However, important challenges exist to deliver sustainable 3D printed cementitious mixtures. Cellulose Nanocrystals (CNCs) and Cellulose Nanofibrils (CNFs) are “green” nanoparticles that can improve the mechanical properties of cement-based materials. This presentation discusses the potential use of CNCs and CNFs in 3D printed sustainable cementitious composites to enhance their extrudability, buildability, dimensional stability, and mechanical properties. This study examines the extruded sustainable cementitious composite mixtures with varying binders and mixture proportions and with different dosages of CNCs and CNFs to optimize the formulation for the production of high-performance cementitious composites.
