#76 Special Concretes | Concrete for 3D Printing | Failure Modes | Buildability | Early Age Behavior

Welcome to 'Admixtures and Special Concretes' course ! This lecture focuses on understanding the behavior of 3D-printed concrete layers during the printing process, exploring the challenges of layer compression and its impact on buildability and structural performance. It discusses the influence of yield stress and the time-dependent deformation of concrete layers under the weight of subsequent layers. The lecture emphasizes the need for careful control of printing parameters to ensure proper layer bonding and prevent structural defects. It also touches upon the challenges of reinforcing 3D-printed concrete and highlights sustainability considerations.
