The integration of waste materials in extrudable cement mixtures has the potential to make the construction industry more sustainable by reducing carbon footprints and developing eco-friendly materials. This along with advancements in 3D concrete printing (3DCP) provides engineering and architectural benefits by reducing material waste and costs. In this paper, the impact of waste incorporation on properties of mortar and concrete is examined. The use of waste materials, such as pumice, coal slag, agricultural lignocellulosic residues, and recycled rubber tyres, to improve thermal insulation and durability of cementitious composites is discussed. In addition, the incorporation of air-entraining admixtures with surfactant activity is explored for their indirect effect on thermal behaviour, pore size reduction, and enhancement in concrete properties. This review includes important topics such as a strength resistance to freezing and thawing, fire resistance, plasticising effect, and delay in cement hydration. These findings highlight the benefits of using diverse waste materials in construction, providing a multidimensional approach to waste management, cost optimization, and enhanced construction materials in the context of 3DCP.

“…The concrete materials and mixture design play a vital role in producing a high quality concrete or imparting the desirable characteristics to 3D printable concrete for example producing high performance, ultra-high performance, lightweight, selfhealing, sustainable/eco-friendly 3D printable concretes, and so on. [7][8][9][10] The printing performance is governed by the fresh characteristics of the concrete such as flow, viscosity, yield strength, and green strength and the printing parameters such as speed of nozzle and height, rate of extrusion, and interlayer interval time. [11,12] Thus, selecting suitable materials and mixing proportions is important to control the rheology, buildability, and printability with acceptable mechanical strength and durability of the 3D printable concrete.…”

3D concrete printing (3DCP) is an emerging additive manufacturing technology in the construction industry. Its challenges lie in the development of high‐performance printable materials and printing processes. Recently developed carbon‐based nanomaterials (CBNs) such as graphene, graphene oxide, graphene nanoplatelets, and carbon nanotubes, have various applications due to their exceptional mechanical, chemical, thermal, and electrical characteristics. CBNs also have found potential applications as a concrete ingredient as they enhance the microstructure and modify concrete properties at the molecular level. This paper focuses on state‐of‐the‐art studies on CBNs, 3DCP technology, and CBNs in conventional and 3D printable cement‐based composites including CBN dispersion techniques, concrete mixing methods, and fresh and hardened properties of concrete. Furthermore, the current limitations and future perspectives of 3DCP using CBNs to produce high‐quality composite mixtures are discussed.
