The 3D printing of concrete is an emerging technology that is likely to exert considerable influence on new construction in the near future. Two main advantages of 3DP construction are the ability to produce a more optimised/efficient form of construction and produce structures with complex geometries. Prototypes of 3DP systems are now in development around the globe by academics and practitioners, but technology uptake has been relatively slow to embrace this emerging technology. This is mainly due to the majority of the developments has focused primarily on the equipment and processes, with less attention paid to the fundamental science in particular on the relationships between the underlying aspects of 3DP such as the rheology with delivery and processes as well as hardened properties with structural geometries. This PhD will focus on the development of a 3DP system with the aim of bringing the technology closer to the market. The research will firstly start with the development of practical mix compositions suitable for printing. The research then continues with detailed investigations into the rheological and mechanical properties of the printed concrete cured over an extended period of time. Parallel work will be undertaken on developing a novel 3D printing system which takes into account construction process. Full-scale prototypes will be produced at the end and tested in an attempt not only to showcase the development but also to feed into the development of assessment and design methods. This PhD research would suit someone who is comfortable working in laboratory environment. A good background in concrete engineering and experience in the design of a 3D printing system are a plus.
