A Brief Description of Different Kinds of Shuttering and its Uses

Wooden Shuttering
It is necessary to gain a deep knowledge about everything before using it and when it comes about anything which is related to construction it should delivers perfect result as it directly affects the durability of structure. Any kind of formwork or shuttering is basically or mainly needed when liquid or thick liquid is supposed to be poured on surface specially where there is no base at all. Here these shuttering and formwork act as an base which later on removed once the liquid sets up and gain required strength. So in modern or any kind of construction formwork is necessary in almost all the stages.   

Both the terms either formwork or various types of shuttering oils basically used for the plywood, timber, aluminum,wooden, metal or any other kind of material which is used for providing basic support to the mixture of wet concrete till the time when it dries up or grasp the desired strength. These applications provide support to inclined, horizontal and vertical kind of surfaces and also for providing support for the casting concrete as per the required size or shape. It is also used for giving desired finish to concrete as well. While using shuttering or formwork it is necessary to use mould release oil which will help to remove them easily later.

Usually three types are shuttering which were commonly used they are:
  • Steel shuttering
  • Wooden Planks
  • Temporary Masonry Shuttering for bricks
Steel shuttering:

This type is best because of some reason as the shuttering is of steel it is water tight and can bear the load of concrete easily which is places on the shuttering. It can either be used on vertical or horizontal surfaces or on any other type of surface depend on the work requirements. It gives surface a very fine shine and finishing as well. This shuttering can be easily used as per the drawing of architecture. If further plaster is required it requires low thickness and as the shuttering is water tight the strength which concrete gains is comparatively high as well. 

Wooden plank shuttering:

These type of shuttering is used due to a basic reason as it costs low it becomes very cheap for contactors and it is easily available in market as well. But these kind of shuttering give adverse affect to concrete some of the main disadvantages are mentioned below:
  • These shuttering are not water tight because the size and its thickness differ and they are usually not of same size. Due to which water flows from the cement though joints which results weaken structure.
  • The slab due to this reason does not build in line, and stay weak forever and causes damage soon.
  • Due to leakage it makes the work messy.
Temporary Masonry Shuttering for bricks:

In some scenarios few contractors prefer the usage of brick masonry for beams side and in fascia etc. It is avoided to use because it reduces the strength of concrete as it soaked the water. This types of shuttering is not preferred for usage.
