Shuttering is a vertical temporary arrangement which is arranged to bring concrete in a desired shape. Formwork which supports vertical arrangement is known as shuttering. In a technical point of view, Formwork for columns, footings, retaining walls is called as a Shuttering
Requirements of good formwork
- Strong enough to withstand dead and live loads.
- Capable of retaining its shape by being efficiently propped and braced
horizontally and vertically.
- Joints should prevent leakage of cement grout.
- Should be capable of being removed in various parts without damaging the concrete.
It should be inflexibly built and efficiently propped and supported to hold its shape without undue deflection. The joints in the formwork should be tight enough to prevent leakage of cement grout. … The surface of the formwork should be plain and smooth, and set properly to the desired line and level.
