EPHEMERAL CONCRETE
A Sustainable Concrete Wall Panel Construction Method

After researching various formworks, three different methods were chosen to visualize the possibility: rigid mold, faceted mold, and fabric mold.
The traditional way to make a thin concrete panel is to manufacture a rigid mold. With this approach, the product is exactly same with its design; however, after using that mold, the material of the mold is not reusable. The material of the faceted mold is not reusable, similar to the rigid mold. The only difference is the faceted mold takes a mesh line of the digital model instead of the precise shape of the surface. Fabric mold is usually used for making a bulgy shape, because the shape is determined by the self-weight of the concrete.
The new method for creating a concrete panel is a hybrid of faceted mold and fabric mold. The structure of the mold is made of fish wire following the faceted mesh lines and the surface of the mold is a latex sheet. This is a very light-weight mold, economical and reusable.
