Formwork

Definition

Formwork refers to temporary structures made of wood, steel, or plastic that serve to give shape to poured concrete.

Purpose

The purpose of formwork is to mold and support concrete until it has gained enough strength to support itself. It ensures the concrete sets correctly, in the desired shape and dimensions.

Examples of Use

• In building construction, formwork is used to create columns, beams, and slabs by holding the concrete in place until it cures.
• Civil engineering projects, such as bridges and tunnels, use specialized formwork systems to shape complex structures.

Related Terms

• Shuttering: Another term for formwork, commonly used in the UK and other countries.
• Scaffolding: Temporary structures used to support workers and materials during construction, often used in conjunction with formwork.
• Falsework: Temporary structures used to support formwork and the concrete until it becomes self-supporting.

Notes

Formwork systems can be reusable or single-use, depending on the material and design. Proper design and installation are critical to ensuring safety and the quality of the concrete structure.
