Resilient 3D-Printed Infrastructure with Engineered Cementitious Composites (ECC)

| 摘要： | Conventional construction of reinforced-concrete structures is slow, labor-intensive, and expensive. 3D-printing holds great potential to assist engineers and architects in the construction of fast and economical, yet complex representational infrastructures. One of the biggest barriers to broader adoption of concrete 3D-printing in civil infrastructure is the difficulty of providing printed structural components with reinforcement to achieve sound structural performance under different loading conditions. Hence, it is essential to design a concrete which can be utilized as a rebar-free material through considering both strength and ductility. Recently, the development of Engineered Cementitious Composites (ECC) has neared the possibility to achieve both strength and ductility in the concrete structures without embedding steel reinforcement. ECC has been offered to enhance the problem related to the ductility and low tensile strength of traditional concrete and Fiber Reinforced Composite (FRC). As such, the implementation of intrinsically reinforced cementitious materials has the potential to address this barrier in reinforcement of 3D-printed concrete and yields significant benefits such as an enhanced structural capacity, durability and resiliency. This project proposes the development of ECC materials utilizing readily available ingredients in Region 6 with rheological characteristics tailored specifically for 3D-printing applications. Furthermore, the project aims to conduct a comprehensive evaluation of the hardened properties of 3D-printed ECC specimens, including mechanical tests. |
