So, it becomes necessary to provide some temporary structure to confine and support the concrete unless it gains enough strength for support itself. The shuttering done with steel is known as steel formwork. Crane-climbing: the formwork around the structure is displaced upwards with the help of one or more cranes once the hardening of the concrete has proceeded far enough. It should retain its shape and size with adequate props and braces. It must have enough strength to bear all the loads present during operations and then must hold its shape while the concrete hardens. Types of formwork 1.
