Slab formwork is a temporary structure used in construction to support concrete slabs until they harden and gain strength. It consists of panels, beams, and props that create a mold for the concrete. This system ensures that the concrete maintains its shape and alignment during the curing process. The design of slab formwork can vary based on the size and complexity of the project. Common materials include plywood, steel, and aluminum, which provide durability and stability. Proper installation and removal of slab formwork are crucial to ensure safety and the quality of the finished concrete structure.
