This project aims to develop a novel approach for designing 3D printed concrete (3DPC) by investigating the relationship between interlayer characteristics, pore structure, and strength. Our goal is to establish a customized pore structure model that represents ideal strength for 3DPC. To achieve this, we will adjust the composition of the printed mixture by incorporating recycled cement and industrial slags, which will reduce both carbon emissions and economic costs. By implementing this approach, we can enhance the strength of 3DPC during mix design, without requiring complicated post-bonding work. Furthermore, our low-carbon recipe for the printed mixture will help address the issue of carbon emissions. We believe that this study will offer a new mix design concept for 3DPC that simultaneously satisfies strength and carbon emission criteria.
Successfully implementing this project will demonstrate that the fabrication of low-carbon concrete composites with customized pore structure and freedom of mix design is feasible. This development will not only benefit the field of 3DPC, but also have a significant impact on neighboring disciplines, particularly the advancement of additive manufacturing in the future.
