WORKSHOP 2 Air Cast Concrete
SU Yunsheng, YANG Hao, FAN Ling
This workshop is based on the New Product Development Fund of Tongji Engineering and Industry Research Institute, which is led by Prof. LOU Yongqi, Future Urban Research Center and supported by Youth League Start-Up Center, Fablab, and 021 Incubator.
This workshop pushes the current boundaries of design and construction by introducing innovations in design processes and material fabrication. Tongji University currently sits at the forefront in robotic construction, material research, structural calculation, and actual market applications, and this workshop will study the limitations of 3D printing and explore its influence on the construction industry.
The MINI project is based on a technical patent of Tongji University’s teaching staff and the integrated innovation with collaborations with industry and enterprise. After project design is complete, we will seek the feasibility of this project with low-tech processes and materials. MINI truly encapsulates material innovation, architectural parametric design, product and service development and crowdfunding in one small but ambitious prototype.
AIR CAST CONCRETE
An air-filled film can be used to create a variety of forms as molds for concrete structures. After they are automatically shaped and cut, they will serve as the cast for 3D spraying of concrete. This construction system uses gypsum-based printing. Compared to the production of a conventional room, air-casting reduces material cost by more than 15%, construction labor and time by more than 50%, all the while enhancing user experience and participation.
TARGET OF THIS WORKSHOP & PROCESS
Students will complete at least one Mini and its interior layout. They will research deeply on material, structure and shape through the manual spraying of the model room. They will also learn about the mechanical arm. The process and research results will be fully recorded as content for further exhibition.
1. Two groups of students make the “Board” and “Skin” with the materials and machines prepared in advance.
2. Moulds made for all the units and models such as the vacuum glass, solar panels and prefab bathroom unit on the “Board”.
3. Combine the “Board” and “Skin ”.
4. Spray Concrete; cure; remove formwork.
