The construction sector has experienced remarkable advancements in recent years, driven by the demand for sustainable and efficient building practices. Among these advancements, 3D concrete printing has emerged as a highly promising technology that holds the potential to revolutionize the construction industry. This review paper aims to provide a comprehensive analysis of the latest developments in three vital areas related to 3D concrete printing: sustainable materials, structural optimization, and toolpath design. A systematic literature review approach is employed based on established practices in additive manufacturing for construction to explore the intersections between these areas. The review reveals that material recycling plays a crucial role in achieving sustainable construction practices. Extensive research has been conducted on structural optimization methodologies to enhance the performance and efficiency of 3D printed concrete structures. In the printing process, toolpath design plays a significant role in ensuring the precise and efficient deposition of concrete. This paper discusses various toolpath generation strategies that take factors such as geometric complexity, printing constraints, and material flow control into account. In summary, the insights presented in this paper may serve as guidelines for researchers, engineers, and industry professionals towards sustainable and efficient construction practices using 3D concrete printing technology.

“…The synergistic effect of calcined clays exemplified by kaoliIite, illite, montmorillonite, and limonite (sedimentary rock based on calcite and dolomite) allows the replacement of more than 50% of clinker while retaining mechanical performance and durability [137,142]. The particle pack density can be optimised to improve printability and the increased amount of metakaolin in the calcined clay can overcome problems with extrusion pressure, initial setting time, and compressive strength of the concrete [48].…”

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.

India’s cement industry is the second largest in the world, generating 6.9% of the global cement output. Polycarbonate waste ash is a major problem in India and around the globe. Approximately 370,000 tons of scientific waste are generated annually from fitness care facilities in India. Polycarbonate waste helps reduce the environmental burden associated with disposal and decreases the need for new raw materials. The primary variable in this study is the quantity of polycarbonate waste ash (5, 10, 15, 20 and 25% of the weight of cement), partial replacement of cement, water-cement ratio and aggregates. The mechanical properties, such as compressive strength, split tensile strength and flexural test results, of the mixtures with the polycarbonate waste ash were superior at 7, 14 and 28 days compared to those of the control mix. The water absorption rate is less than that of standard concrete. Compared with those of conventional concrete, polycarbonate waste concrete mixtures undergo minimal weight loss under acid curing conditions. Polycarbonate waste is utilized in the construction industry to reduce pollution and improve the economy. This study further simulated the strength characteristics of concrete made with waste polycarbonate ash using least absolute shrinkage and selection operator regression and decision trees. Cement, polycarbonate waste, slump, water absorption, and the ratio of water to cement were the main components that were considered input variables. The suggested decision tree model was successful with unparalleled predictive accuracy across important metrics. Its outstanding predictive ability for split tensile strength (R2 = 0.879403), flexural strength (R2 = 0.91197), and compressive strength (R2 = 0.853683) confirmed that this method was the preferred choice for these strength predictions.
