What does formwork refer to in construction?

Formwork refers specifically to the temporary molds utilized in construction for shaping poured concrete. This crucial element in concrete work ensures that the concrete takes on the desired shape and supports itself during the curing process until it gains sufficient strength. The formwork is typically made from materials like wood, metal, or plastic, which can be easily assembled and disassembled.

Using formwork allows for versatility in designs and is essential for various structural elements such as walls, slabs, and columns. Once the concrete sets and reaches proper strength, the formwork is removed, allowing the completed structure to stand independently.

Other choices, while related to construction, do not accurately define formwork. Permanent structural supports would refer to components that are meant to remain in place, insulation materials serve to enhance thermal efficiency, and finished surfaces pertain to the final look of walls and ceilings, none of which capture the temporary, shaping function of formwork.
