Fractal-Based Porous Concrete Components Design and 3D Printing

This chapter explores the innovative application of fractal geometry in the design of extra-light porous concrete structures utilizing advanced 3D printing technologies. It methodically examines various fractal-based modeling approaches, including form-based, force-based, and fabrication-aware strategies, each contributing uniquely to the development of specialized light porous concrete structures. This chapter further explores two distinct fabrication techniques: the utilization of 3D-printed polymer formwork for casting concrete components and the cutting-edge method of directly 3D printing concrete mixed with polymers, which remarkably eliminates the need for conventional formwork. Additionally, this chapter discusses the intricacies of composite concrete mixtures tailored to suit the specific modeling approach, fabrication method, and intended application of the components. Rather than presenting new empirical findings, this chapter serves as a synthesis of existing research and studies in this field. Its aim is to illuminate the potential and expand horizons for the application of fractal concepts in the realm of 3D-printed concrete structures. This exploration not only highlights current opportunities but also opens up avenues for future possibilities, showcasing how the convergence of fractal geometry and 3D printing technology can lead to significant advancements in construction methodologies and materials.
