Some properties of 3D Printing Concrete Mixtures (3DPC) need to be developed in order to make them widespread in the construction industry. The amount of cement used to provide extrudability in 3DPC mixtures is quite high compared to conventional concrete mixtures. This situation negatively affects the sustainability of 3DPC mixtures as it is not ecological and economical. In this article, the development, advantages and production process of 3DPC mixtures from past to present are mentioned. In addition, the use of mineral additives such as fly ash, silica fume, blast furnace slag and other waste materials instead of cement for the production of sustainable 3DPC mixtures was investigated. Also, the possibilities of using other aggregates such as recycled concrete aggregate and desert sand in 3DPC mixtures were investigated. Within the scope of the study, the rheological properties of 3DPC mixtures were examined. In addition, the interlayer adhesion properties, which is another obstacle to the widespread use of 3DPC mixtures and the parameters affecting the interlayer adherence were investigated.
