Concrete formwork explained

Formwork is structural and is the term used for specialised concrete construction moulds. Wet concrete is poured into these supportive moulds, which are usually temporary, to set and take form until it can support itself.

The concrete formwork process is often referred to as shuttering, which is typically made from timber—although some contractors use reinforced plastic, steel or fiberglass.

Often, once the concrete structure has set and deemed safe, the formwork is safely removed from site.

The importance of formwork

Any aspect of a construction project that offers support and structural safety is essential—formwork is no exception.

Not only does the right kind of formwork improve site safety and provide vital support to certain elements of a building’s design in those vital early stages, but these ancillary structures also ensure the smooth running of a construction project while increasing the overall quality of the finished structure.

Here are the key qualities of good formwork:

• Can withstand both live and dead tools.

• Will help to achieve your preferred concrete shape and finish.

• Sets complete accurately in along your desired line.

• Is easy to remove without damage and is as lightweight as possible.

• Won’t warp or lose form when exposed to extreme external elements like heat and can reset, with ease, on a firm base.

• Is constructed to meet your specific project needs and requirements.

As we said, the formwork can make the difference between building success and failure. Without formwork, you run the risk of running into no end of struggles or calamities during the concreting phase of your construction project.

Formwork in concrete construction, also called shuttering, is a structural mold in which fresh concrete is poured and hardened. Here are some things you should know about concrete formwork:

1) Formwork Makes Up to 25 Percent of the Cost of a Structure

The construction of concrete formwork is no small undertaking; it takes time and can cost up to 25 percent of the total price of the structure. Luckily, stripped concrete formwork can be reused to reduce time and cost. Reusable forms are known as “panel forms,” while non-reusable concrete forms are called “stationary forms.”

2) Timber Is the Most Common Formwork Material

Across the different construction sectors, timber is the most common material used for concrete formwork. The timber should be well-seasoned, lightweight, easily workable, and free from loose knots. The downside of using timber concrete formwork is that it will warp, but the application of water-based treatments to the surface of the wood can help reduce this effect.

3) Steel, Plywood and Fiberglass Are Also Used In Formwork

In addition to timber, concrete formwork can be made out of steel, plywood, and fiberglass. These materials can be used separately or together.

The most common type of concrete formwork used in heavy civil construction is steel! Steel formwork consists of panels created from thin steel plates that are stiffened along the edges by small steel angles. The panel units are held together with clamps or bolts and nuts, and can be produced in large quantities in any shape or size. Steel formwork is stronger, more durable and has a longer life than timber formwork, and it will not shrink or warp.

Formwork can also be crafted from resin-bonded plywood sheets. The sheets are attached to timber frames to make up the formwork’s panels. The cost of plywood formwork is comparable to that of timber formwork, and can sometime be cheaper.

Fiberglass made of precast concrete and aluminium is used in cast-in-situ construction such as slabs or projects involving curved surfaces.

4) A Good Formwork is Strong But Light

A good formwork should be strong enough to withstand all types of loads, but it should also be as light as possible. The formwork should be constructed rigidly and braced both horizontally and vertically, so as to retain its shape. Similarly, the joints in the formwork should be tight against leakage and should rest on a firm base.

5) The Cost of Formwork Can Be Reduced

Though formwork constitutes a large portion of the cost of a structure, these costs can be reduced. In order to reduce the cost of formwork:

• The plan of the building should include a minimum number of variations to the sizes of the rooms so that the formwork can be reused

• The design of a building should use as few slender sections as possible

• Minimum sawing and cutting of wooden pieces should be made so that the material can be reused multiple times

• Formwork Can Sometimes Be Removed Early

Quickly hardening cement, warm weather and light loading conditions can allow for the early removal of formwork. Formwork should not be removed until all the concrete is able to withstand at least twice the amount of stress and pressure that the structure is expected to undergo. No matter when the formwork is removed, it should always be eased away gradually so that the load is slowly transferred to the concrete.

7) Steel Formwork Can be Resold

Because of its strength and long working life, there is a great used market for concrete formwork made of steel. Reselling concrete formwork after a project is a great way for contractors to make money. In addition, purchasing used and surplus formwork for a project is an equally great way for contractors to save money.
