Formwork for Concrete and Its Properties

A formwork for concrete is utilized as a mould for a structure where fresh concrete is being poured only to harden afterwards. The kind of concrete formwork construction will be dependent on the formwork material, as well as the type of the structural element.

Formworks are also named based on the type of structural members like slab formwork which is for use in slab. There is also beam formwork and column formwork to be used in beams and columns.

The construction of a formwork would often take time and involves an expenditure of up to 20-25% of the total price of the structure or can be even more. The designs for these temporary structures are created to economic expenditure. The process of removing the formwork is called as stripping in which the stripped formwork can still be reused. The reusable forms are known as panel forms while the non-usable ones are stationary forms.

Timber is among the most common materials used for formwork. However, one of its disadvantages is that it swells, warps, and shrinks. A good formwork should be able to satisfy the requirements below.

  • In needs to be firmly constructed and proficiently braced and propped vertically and horizontally so it maintains its shape.
  • The joints in the formwork need to be right against leak of cement grout.
  • The construction of formwork needs to permit the removal of different parts in the anticipated sequences without damaging the concrete.
  • The material of the formwork needs to be cheap and readily available and be suitable for reuse.
  • The formwork needs to be set precisely to the desired levels and line and have a plane surface.
  • It needs to be as light as possible.
  • The material of the formwork need not warp or become distorted when visible to the elements.
  • It needs to rest on a firm base.


Economy in Formwork

Here are some points that need to be kept in sight to effect economy on the cost of formwork.

  • The plan of the building needs to suggest minimum number of differences in the room size, floor area, etc. to allow the reuse of the formwork.
  • The design needs to be perfect to utilize slender sections in the most economical way.
  • Minimum cutting and sawing of wooden pieces need to be made to allow reuse of the material. The quantity of the surface finish is dependent on the quality of the formwork.

Formwork for concrete can be made out of plywood, timber, plywood, fiberglass, precast concrete used separately or in combination. Steel forms are utilized in situations where large numbers of reuse of the same forms are needed. In the case of small works, timber types will prove to be useful. Fiberglass that is made of precast aluminum and concrete are used in cast in site construction like members or slabs involving curved surfaces.


3D Printers Melbourne: Benefits You can Never Ignore

When it comes to product development, the new technology really has a role to play, being one of the best sources of information for one. Today, one of the most evident shifts in product development is the great impact brought by 3D printers Melbourne on rapid prototyping. If you want to know what these impacts are, they are listed as follows.


Time to Market

3D printers Melbourne have allowed more ideas to develop faster than ever before. You can now 3D print a concept on the very same day that it was designed. This shrinks the development process from what could have been finished in months to just a few days, thus helping companies to get ahead of the competition.


More Savings

The tools for prototyping injection and production runs can be very expensive. But with 3D printing, the process permits the creation of different parts and even tools through the process of additive manufacturing at rates that are much lower than using traditional machines.


Mitigate Risks

It is now possible to verify a design before you can invest big amounts of money for molding tools. Printing a production-ready kind of prototype will build confidence prior to making large investments. At the same time, it is cheaper to print a test prototype in 3D than to alter an existing mold or to redesign it.



Since you have the prototype at your disposal, you can test the market by unveiling it in trade shows, showing it to potential investors and buyers, or even to raise capital by pre-selling. Getting responses from buyers before allowing the product to go into production is one great way to verify the potentials of the product in the market.


Get the Feel

Feeling the actual product is never possible with virtual prototypes on the computer screen. If you would like to ensure the ergonomics and the right fit of the product, you need to be able to hold, use, and even test it. This is something that can done with 3D printing.


Personalize It

Given standard mass-production, parts may come off the assembly line or even out of the mold. But with the help of 3D printing, you can customize, personalize, or even tweak a part in order for it to fit the needs. This permits custom-fits in dental and medical industries and even helps people set apart in the jewelry and fashion world.

These are just a few benefits that this new technology can bring to the world. Day by day, it is giving people more reasons to live a better and more comfortable life. 3D printing has indeed made all our lives more convenient and has given us the best results- the ones that we deserve. It is also no wonder why so many businesses today involve the use of this technology.
