Shuttering or formwork is the term used for temporary timber, plywood, metal or other material used to provide support to wet concrete mix till it gets strength for self support.
Formwork (Shuttering) is temporary support as a mould for fresh concrete, in which concrete is poured and cast in the desired shape and gain initial strength, hardened and matured. Formwork is used in different shapes and sizes according to our construction elements in the form of PCC, RCC works in Building, Bridge, Tunnel Lining, Hydropower Dam, Irrigation Headwork, Sanitary Pipeline work, etc.
The cost of formwork is considered as 20 to 25% of the cost of the structure in building work, it may be higher than this in bridges. In order to reduce the cost of form, it is necessary to design economical types of formwork and to mechanize its construction.
We should have to remove the form work when concrete has reached a suitable strength. That process of removal of formwork is also called stripping. After stripping of form it’s components are removed and can be used in other construction processes or other parts of work. The repeatable type of formwork components is known as a panel form.
