Abstract
The construction industry is one of the largest industries in the world by size, investment, labor, material use, and energy consumption. As a result, it has been lagging behind in terms of automation as compared to many other industries which have evolved more rapidly over the past decades. In spite of various attempts to introduce automation, the industry remains labor intensive. In this chapter, we explore the promises, successes and challenges that Large Format Additive Manufacturing (LFAM) brings in the field of construction as it applies to cementitious and geo materials. Cementitious materials are any composites that are cemented (glued) together using a binder. However, the word “cementitious” has been considered to relate to hydraulic cements that are mainly made of Portland cement and supplementary cementitious materials (SCMs) like fly ash, silica fume, and others. Therefore, the term “geo” here refers to earth materials used as is like clays. The section discusses the needs for construction LFAM, the components of a construction LFAM system, and the steps necessary to build a structure using construction LFAM technology.
