Formwork (shuttering) in concrete construction is used as a mould for a structure in which fresh concrete is poured only to harden subsequently. Types of concrete formwork construction depends on formwork material and type of structural element.
Formworks can also be named based on the type of structural member construction such as slab formwork for use in slab, beam formwork, column formwork for use in beams and columns respectively etc.
Timber is the most common material used for formwork. The disadvantage with timber formwork is that it will warp, swell and shrink. Application of water impermeable cost to the surface of wood mitigates these defects.Reusable forms are known as panel forms and non-usable are called stationary forms.
Formwork refers to either temporary or permanent moulds which hold materials like concrete. Timber formwork takes the form of a structure of boards surrounding an open cavity, and offers several advantages over other formwork types.
Painted timber formwork not only adds color and a finished look, but oil or epoxy treatments can double the number of times the formwork may be reused.
