Quality of Formwork For Concrete Construction and Its Features

In concrete buildings, formwork is used as a mould for a structure into which fresh concrete is poured and then hardened. For premium quality, they need to be purchased from the reputed and best Highway Metal Beam Crash Barrier Manufacturers in Kolkata. 

There are many types of concrete formwork construction that are determined by the formwork material and the structural element. 

Formworks are dependent on the type of structural member construction, such as slab formwork for use in a slab, beam formwork, column formwork for use in beams and columns, and so on. This type of construction takes time. These temporary constructions are designed to save money. 

Conditions For Premium Quality Formwork

• It should be capable of withstanding all forms of dead and live loads. To keep its shape, it should be solidly built and efficiently propped and braced both horizontally and vertically.

• The formwork joints should be tight to prevent cement grout from leaking. The design of the formwork should allow for the removal of various pieces in the required sequences without causing damage to the concrete.

• The material used for the formwork should be inexpensive, easily available, and reusable. The formwork should be precisely positioned to the required line, and the levels should have a smooth surface.

• It needs to be as light as feasible. When exposed to the environment, the formwork material should not bend or become distorted and should be supported by a solid foundation. These quality formworks are available only from the top Highway Guardrail Suppliers in India.

Categories of Formwork

There are three categories of formwork required for the construction process 

Timber Formwork

This type of formwork should be well-seasoned, light in weight, work easily with nails without cracking, and be free of loose knots. The timber used for shuttering for exposed concrete work should have a smooth and even surface on all faces that come into touch with the concrete.

Plywood Formwork

To manufacture panels of the requisite sizes, resin-bonded plywood sheets are affixed to timber frames. The cost of plywood formwork is comparable to that of timber shuttering, and it may even be less expensive in some cases if it is possible to achieve a smooth finish, in which case there is a cost in surface finishing. 

The usage of large-size panels can result in labor cost savings for fixing and dismantling. When compared to wooden shuttering, there are more reuses. 

Steel Formwork

This is made up of panels made of thin steel plates that are stiffened along the edges by small steel angles. They are commonly employed in large projects or situations where the shuttering can be reused multiple times. This style of shutter is best suited for round or curved constructions.

Formwork can be built using these three alone or in combination. JBFS Engineering System Pvt Ltd also has all these three types of formworks.

Conclusion

The formwork should be built of high-quality materials and appropriately constructed. The formwork material should be inexpensive, readily available, and reusable and should be purchased from the largest Highway Guardrail Exporters in India. This technique of shuttering offers the requisite grade surface finish. 

The material chosen for formwork is determined by the nature of the structure as well as the availability and cost of the material for safe and premium construction.
