What is the purpose of using "formwork" in concrete placement?

The purpose of using formwork in concrete placement is primarily to shape and support the concrete until it cures and gains the necessary strength. Formwork acts as a mold that holds the wet concrete in the desired shape and configuration while it hardens. This allows for the creation of various structures and surfaces, ensuring that the concrete maintains its intended form during the curing process.

As the concrete sets and develops strength, the formwork provides the necessary support to prevent deformation or sagging. Once the concrete has cured sufficiently and has gained adequate strength, the formwork can be removed, leaving a well-defined surface that adheres to the planned specifications. The stability offered by formwork during curing is crucial for ensuring the final quality and integrity of the concrete flatwork.

While curing the concrete properly is essential for achieving strength, formwork does not facilitate the curing process itself directly. Instead, it provides a temporary structure that aids in maintaining the shape and alignment of the concrete during this vital period. Other functions, such as promoting surface finishing or adding decorative patterns, are secondary to the primary role of formwork in shaping and supporting the concrete.
