As an ancient building material, concrete has been used for thousands of years in human construction civilization. In the field of digital design, concrete material is used by many research teams for innovative application research of digital construction because of its unique material properties and cheap raw material sources. This project proposes a physical form finding design method of concrete flexible formworks generated by computational algorithm, which aims to explore the potential formal association between real material as the medium of information transmission in physical space and virtual data, so as to discuss the autonomy and intelligence of material under the application of digital design technology. In the first part of this paper, the application and development of concrete materials in the field of digital construction in recent years are discussed, and then the adaptability of flexible formwork to the fluidity of concrete materials is studied. Then, the pouring method of concrete physical shape finding by flexible and rigid composite formwork system is built, and the formwork shape under the control of computational algorithm is explored. In this combination formwork system, two different material are applied to explore the shaping potential of concrete. In the frame part, we use laser-cut wood plank to make the whole rigid formwork structure. For the purpose of efficient and cheap, wood and nylon are used as the main material of concrete formwork , which both show environment-friendly characteristic. By adding soft wave material among this support structure, It will form an ambiguous space with both rigidity and flexibility, in which concrete is able to form a soft shape due to the combined action of gravity and surface pressure of fabric. The next part records the plastic process of concrete pouring experiment under this method to discuss the internal relationship between the physical form of concrete and the digital template. Under the restriction of the formwork generated and processed by digital tools, the state of concrete combines the free flow characteristics of its own material attribute and the control of the environment under the restriction of combined concrete formwork. In the conclusion part, this paper discusses the construction practicability of this method, and puts forward the design potential of the concept of “form follows material”.
