INDEX Defination of Form work Necessity of Form work Requirements Types of Form work Fibre Shuttering What is Form work ? Form work is defined as ‘complete system of temporary structure build to contain fresh concrete so as to form it the required shape and dimensions and to support it until it hardens sufficiently to become self-supporting’ It is also known as shuttering. Necessity of Form Work To give required shape to the concrete. To ensure stability for dead and live loads such as loads of workmen, equipment, etc. To prevent exposure to direct sun rays or rain water. To prevent loss of water. To ensure easy curing of concrete. Requirements A good form work should satisfy the following requirements: The material of the form work should be cheap and it should be suitable for re-use several times. It should be practically water proof so that it does not absorb water from concrete. It should be strong enough to withstand all loads coming on it. It should be stiff enough so that deflection is minimum. The form work should rest on non-yielding supports. Types of shuttering Timber shuttering Plywood shuttering Steel shuttering Fibre shuttering Timber Form work Plywood Form work Steel Form Work Timber Form Work: The Timber shuttering is the most widely used and universally adopted form work material. It is cheaper, easily available, easy to fix, impact resistant, easy to remove, can be used several number of times, can give large level surface and can be used to obtain any geometrical surface. Plywood Form Work: Plywood sheets bounded with synthetic resin adhesive are being widely used now-a-days. The thickness of ply varies from 3 to 18 mm. The main advantage is that large panel surfaces are available. The fixing of forms is rapid and economical. It does not warp, swell and shrink during the setting of concrete. Moreover, it has high imapct resistance. Steel form works are commonly employed for big projects, where the forms are to be repeatedly used. The steel forms can be easily fabricated and do not require many adjustments as the units are standardized. Steel form work is very strong. They are easy to assemble, give smooth surface, High strength and impact value, easy centering. Steel form works are commonly employed for big projects, where the forms are to be repeatedly used.
