A Critical Review of Fresh, Hardened and Durability Properties of 3D Printing Concrete
摘要
Geometric complexity in construction can be easily achieved through 3D printing technology when compared to tradition construction technology. Effective use of 3D printing technology in construction of buildings can lead to reduced usage of materials and energy, flexibility in design, cost and time consumption. This review article mainly focuses on the research contributions pertaining to fresh, hardened and durability properties of 3D printing concrete. Furthermore, emerging techniques and materials used in 3D printing construction, challenges in implementation and corrective measures to increase the feasibility of using 3D printing technology in the field of construction technology have been elaborately discussed in this study. Critical review of literatures proved that the workability, strength and durability performance of 3D printing concrete are effectively enhanced by appropriate mix design and the performance of 3D printing concrete can be improved by including suitable fibers, mineral admixtures and chemical admixtures.
