What is the purpose of shuttering?
Shuttering, also known as formwork, is a temporary structure used in construction to shape and support poured concrete or other materials while they harden and gain sufficient strength to support themselves. Its purpose includes:
1.Shaping the Concrete: Shuttering acts as a mold to shape the concrete into the desired form and dimensions, whether for walls, slabs, columns, beams, or other structural components.
2.Providing Support: It holds the weight of the fresh, wet concrete and any reinforcement until the concrete sets and becomes self-supporting.
3.Ensuring Surface Finish: Properly constructed shuttering ensures a smooth and uniform surface finish for the concrete, reducing the need for additional finishing work.
4.Maintaining Structural Integrity: By holding the concrete in place during the curing process, shuttering helps maintain its structural integrity and prevents deformation or collapse.
5.Facilitating Complex Designs: For architectural or complex shapes, shuttering allows for intricate designs, curves, or patterns in concrete construction.
Shuttering materials can include:
● Timber: Lightweight and easy to shape but less durable.
● Plywood: Commonly used due to its smooth surface and reusability.
● Steel: Durable and ideal for repetitive use in large projects.
● Plastic or Fiberglass: Lightweight and good for curved or decorative shapes.
Shuttering is removed once the concrete has gained enough strength, in a process called stripping or de-shuttering.
