3D concrete printing: Variety of aggregates, admixtures and supplementary materials

This review paper provides a report on the up-to-date research on the 3D printing technology for the concrete in terms of materials. It reviews the required characteristics of concrete rheology, printing process and discusses the challenges for reaching compatible mix proportions using eco-friendly binders, aggregate, and chemical admixtures. The recent research on the durability behaviour of 3D printed concrete needs future research and identification.
