What is the primary purpose of using sheathing in concrete construction?

The primary purpose of using sheathing in concrete construction is to hold concrete in place until it sets. When concrete is poured, it is in a fluid state and requires support to maintain its shape and structure while it cures. Sheathing provides the necessary formwork that defines the desired shape of the concrete and prevents it from leaking or spilling out before it hardens. This ensures that the concrete can gain its strength and integrity as intended.

In addition to maintaining shape, sheathing also helps to prevent any premature exposure to environmental elements that might affect the curing process. Therefore, it plays a crucial role in the successful completion of concrete projects by ensuring the concrete remains contained and properly shaped during the critical initial setting and curing phases.
