What is the name of the mold used to maintain the shape of concrete before it sets?

The term for the mold used to maintain the shape of concrete before it sets is "formworks." Formworks are essential in the construction process as they provide the necessary structure to hold the wet concrete in place until it hardens and can support itself. They can be made from various materials, including wood, metal, or plastic, depending on the shape and size of the concrete structure being formed.

The role of formworks goes beyond just shaping; they also ensure that the concrete elements maintain their dimensions and surface finish during the curing process. Without properly designed and constructed formworks, the final product may suffer from structural deficiencies or aesthetic imperfections.

In contrast, shoring refers to the process of supporting a structure temporarily during construction, centres are primarily used in the context of arches and domes to provide support during the setting of the concrete, and scaffolding is a temporary structure used to support workers and materials during the construction or repair of buildings and other large structures. Each of these terms serves a different purpose in the construction process, which further emphasizes the specific role of formworks in maintaining the shape of concrete.
