What is formwork?

Formwork is the term used for the process of creating a temporary mould into which concrete is poured and formed. Traditional formwork is fabricated using timber, but it can also be constructed from steel, glass fibre reinforced plastics and other materials.

What is the purpose of formwork?

The formwork serves as mould for concrete structural components unless such mould is provided by the soil, other structural components, etc. It moulds the placedfresh concrete, which in this stage normally is viscous, to the shape specified in the drawing.

What are the types of formwork?

The Different Types of Formwork Used in Concrete Construction

  • Traditional timber formwork.
  • Engineered Formwork System.
  • Reusable plastic formwork.
  • Permanent Insulated Formwork.
  • Stay-In-Place formwork.
  • Flexible formwork.

What is formwork and types of formwork?

Formwork ( shuttering ) in concrete construction is used as a mold for a structure in which fresh concrete is poured only to harden subsequently. Stripped formwork can be reused. Reusable forms are known as panel forms and non-usable are called stationary forms. Timber is the most common material used for formwork.

How is formwork calculated?

The formwork is measured in terms of area that is in contact with the concrete surface.

Bottom of the footing is resting on earth, there is no need of any formwork and top of footing is open.

What is difference between formwork and shuttering?

Formwork is the overarching term that’s used to describe the forming process. Shuttering is defined as the temporary moulds that are used to hold the wet concrete in place until the concrete has set and cured.

What is the importance of formwork in construction?

Formwork allows for the construction of custom slabs and columns on site to speed up and enhance the construction process. It provides the mould in which the fresh concrete is poured, allowing it to then harden in this predetermined shape, perfect for the construction purpose it is intended for.

What are the components of formwork?

Reliable quality and consistent supply of new formwork components, such as three-ply panels, plywood sheets, formwork beams and floor props.

What are the requirements of formwork?

Requirements of good formwork:-

  • It should be adequately strong to withstand an extensive variety of dead and live loads.
  • It should be inflexibly built and efficiently propped and supported to hold its shape without undue deflection.
  • The joints in the formwork should be tight enough to prevent leakage of cement grout.

What is beam and slab formwork?

Forms are molds to receive concrete in its’ plastic form. Formwork is temporary structure, as such, it is not normally shown on the drawings.
