Concrete 3-D printing team: Final report

Abstract

3D Concrete Printing has been a multi-semester research project, having a new interdisciplinary team every semester. The goal of the project is to develop a working system that can be used in the field to 3D print concrete. This is to eventually provide cheaper, safer homes throughout the world. The Spring 2020 team was challenged with getting the delivery system working, making a skid steer autonomous, and continuing the investigation into printable concrete. As part of the civil engineers on the team, this report focuses on the concrete research done this semester. As the Fall 2019 team found a working concrete mixture, the Spring 2020 team investigated the in-place concrete properties such as strength, density, and aesthetics. The findings of this research along with some of the electrical and mechanical engineers research can be found in this report.
