Abstract

Additive manufacturing of concrete, also known as 3D printing of concrete, is a rapidly emerging construction technology that eliminates the need for conventional formwork while fabricating concrete components with complex geometries through a layer-by-layer buildup process. This technology can significantly improve productivity, reduce labor demands, and decrease carbon emissions. However, the use of high ordinary Portland cement (OPC) content in printable concretes compensates the environmental advantages offered by this technology. Currently, there are two approaches, namely replacing OPC with sustainable alternative OPC-free binders, and partially substituting OPC with high volume of supplementary cementitious materials (SCMs). In this chapter, several promising OPC-free binder systems and high-volume SCMs mixtures were reviewed, highlighting their main advantages and challenges within the context of this technology.
