Formwork in construction - this auxiliary structure of wood, metal, or other material that serves to give a monolithic designs from concrete, reinforced concrete, soil mix, other construction of solutions of certain parameters such as shape, geometry, position in space, surface structure, etc. Shuttering or formwork system consists of formative elements, support structures and fastening. After curing of the mortar, the formwork is usually removed. The process of dismantling the formwork is removed is called. The basic requirements that must be met for construction formwork, it is strength, dimensional stability and position in space. From the casing also determines the quality and texture of the surface of monolithic structures.
