Abstract This paper reports a radical departure from generally accepted concepts in construction-automation and demonstrates that new techniques of layered manufacturing can be applied effectively to construction. In the process, we also modified material processing of cement to adapt it to the requirements of Solid Freeform Fabrication. Our purpose is illustrated with sample structures manufactured by incremental deposition of reactive bulk materials (cement and Silica in this instance), a characterization of their material properties, and an assessment of their potential for Solid Freeform Fabrication of large structures. For example, we estimated that it it would take about 2.5 months to build a structure the size of a 3000 sq. ft. house. Keywords: Selective aggregation, Large structures, Functional Prototypes, Multimodal structures, Construction Automation. (Auth abstract) [References: 7]
