Resilient 3D-Printed Civil Infrastructure with Ultra-High Performance Engineered Cementitious Composites (UHPECCs)

The advent of construction 3D printing (3DP) technology has opened the possibility of revolutionizing construction productivity worldwide. However, one important barrier for broader adoption of construction 3DP in civil infrastructure is the difficulty to provide printed structural components with reinforcement to achieve sound structural performance under different loading conditions. As such, the implementation of intrinsically reinforced cementitious materials has the potential to address this barrier and yield significant benefits such as an enhanced structural capacity, durability, and resiliency. For this reason, novel ultra-high strength highly ductile cementitious composites such as Ultra-High Performance Engineered Cementitious Composites (UHP-ECCs) are excellent candidates for the 3DP of structurally sound civil infrastructure. This project proposes the development of UHP-ECC materials with rheological characteristics tailored specifically for construction 3DP application. Furthermore, this project aims to conduct a comprehensive evaluation of the hardened properties of printed UHP-ECC.
