| Abstract Scope |
Additive Construction (AC) technologies can provide many advantages over conventional concrete construction techniques. Mix design for AC is more complex than conventional concrete casting due to the need for the mix to be pumpable, extrudable, and buildable. This study explores the design of concrete mixes for use in AC applications. The ability of layers to be deposited on top of one another, while maintaining the desired geometry, and without significant slump was explored. One of the goals of this study is to be able to utilize indigenous materials from expeditionary environments within AC concrete mixes, while maintaining reasonable mechanical properties. The ability to utilize materials available on-site for construction is significantly more economical than transporting them over long distances. The AC printing system, and path planning for large concrete articles will be discussed. Cores were removed from printed articles to evaluate compressive strength and split-tensile strength. |
