Basic Difference Between Shuttering and Formwork

Formwork Shuttering Systems
We all are very much aware with the terms shuttering and formwork. They are very useful in construction industry but its usage is not limited to this sector only in all the manufacturing arenas shuttering is necessary and framework is also necessary is so many fields. Here we are going to discuss about the difference between formwork and shuttering.

Initially it is important to understand the basic work of both shuttering and formwork. Working arena of both is same. It is used in such process while creating molds in these concrete is poured and left until it sets properly and hardens up for the required shape. The basic use of these two is this only.

The term shuttering commonly refers for the process in which plywood’s are used to form mold, and to release these moulds further shuttering oil is applied on shuttering before placing it anywhere. These molds can be placed in such a way that it can support the entire structure mainly the fresh concrete poring for slabs etc and keep on that place until the material grab the require strength then shuttering is removed from that area.

Apart from shuttering, framework is something which is broad and basically used for the forming process in various materials. At initial level the work of shuttering and formwork seems to be similar but later the material which accomplished in both may vary which causes the difference between both. At some situations both the terms comes as came there is no difference at all and at few stages shuttering is also considered as a type of formwork.

It is necessary to know the basic difference between both the techniques because at some aspect only a special thing can work out it may be shuttering or it may be formwork what matters most knows about both the applications and it usage properly to retain best possible results. Both differ slightly but at a point this slight difference can make huge impact on the material which is going to be placed on any of them. It affects the durability and life of newly placed layer on any of them either on formwork or on shuttering both acts as mould. While in shuttering there is a need of applying oil to release the material from mould.     

No matter how large or small the size of project is all needs to employ both the techniques either formwork or shuttering in projects which are normally large scale requires different kind of formwork while on other hand shuttering is used in a wide way in industry because it is very easy to use and at a time huge amount of concrete can be poured. Shuttering is something which causes costs low because normal plywood can be used in shuttering and it can be re use again and again for the same purpose. But few things which should be taken in mind that special quality of plywood should be used in shuttering or in formwork make sure that both are water resistant as almost all the concrete projects were usually performed outdoors.

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.

Role of Curing in Construction

Curing of Concrete
We all are very much familiar with the word curing as it comes in our day to day routine. It may be related to building, lighting or to any other stuff. Here we are talking about curing of concrete. We all are very well known that concrete act as a key material in almost all types of building and various construction processes. What makes essential to cure concrete is if it does not cured in initial stage it dries up quickly and loose all the inside moisture due to which the structure strength and life will decrease and the surface will lead towards cracking and damaging.

Or in other words it is a process which is adopted widely for hardening the surfaces of concrete under hard conditions such as humidity & the temperature which is favorable to proper and cumulative settings of cement. Curing affects in a huge way on the concrete from both inside as well as from its outside surface. As it helps it to harden in a better way it also increases the durability, volume stability, strength, wear resistance, freezing, water-tightness and thawing.

No matter how perfectly you mix, placed or finished concrete without perfect curing all the efforts are useless.Now when we are clear with the concept why curing is necessary it is essential to be aware of various cuing techniques and which one is best among them.

When we are talking about building construction we all know that after making slabs and floors people use to pour water and fill that place with it just to maintain the outside temperature cool and to look moisture of concrete inside it but this technique require more time, more labor, more expense and lots of attention plus the technique is not environment friendly because it results wasting natural resource for unwanted and unnecessary reasons.

Moving towards another option for curing which sounds more reasonable, eco friendly and requires almost no attention and you don’t have to keep us the record of how many days left till you can use the surface.

That technique is called 'Curing Compound'.  There are so many varieties available in market such as oil based, PVA based, rubber based, resin based, wax based curing compound. All of them are colored which fades by time only the wax based curing compound is white in color.

It can be easily sprayed on any surface especially on cement roads, concrete pillars with the help of spraying pump it is necessary to spray this wax based white colored liquid just after it dries a bit. The wax based film breaks by passing time when the surface gets in touch with sunlight continuously.

This application saves your time and money both its better to upgrade your construction process with new chemicals which makes you work more easily as compared with your experience with old techniques. Adopt the usage of curing compound and contribute in saving natural recourses, time and money. About wax based curing compound uses, advantages, properties etc.
