Abstract

In spite of exploratory structural applications, 3D concrete printing technology remains fragmentary, and its full-scale uses in transportation infrastructure are still rarely seen. In order to bring the full benefits of this technology to the construction industry, it requires a much better understanding of the relationships among digital design, operation/processing, mechanisms of building materials, formulation of printing materials, and performance of printed products. The goal of the project was to apply three-dimensional (3D) concrete printing technology to transportation-related infrastructure. The specific objectives were as follows: Develop a printable and functional 3D printing concrete mixture using materials commonly available in Iowa Characterize the 3D printed concrete properties and better understand the requirements of 3D printing technology to develop concrete mixtures Explore the potential applications of 3D printed concrete in the field of transportation engineering, realize the challenges and future perspectives, and lay a foundation for extended studies and applications of 3D printed concrete in Iow
