- Q: How does steel formwork prevent concrete spalling?
- By offering a robust and inflexible framework, steel formwork effectively prevents concrete spalling. This framework securely holds the concrete in place while it undergoes the curing process. When the concrete is poured into the steel formwork, it assumes the shape of the structure and gradually hardens. The steel formwork guarantees the concrete's stability, preventing any sagging or slumping that could result in uneven curing and subsequent cracking. Concrete spalling arises when the surface of the concrete begins to flake or chip away, thereby exposing the underlying layers. This deterioration can occur due to various factors, including moisture infiltration, freeze-thaw cycles, and chemical reactions. Steel formwork serves as a protective barrier against these external influences, effectively thwarting spalling. The snug fit of the steel formwork impedes water from permeating the concrete, thus reducing the risk of moisture-related spalling. In addition, this formwork acts as insulation against temperature fluctuations, thereby minimizing the detrimental effects of freeze-thaw cycles. These cycles transpire when water infiltrates the concrete, freezes, and expands, leading to cracks and spalling. By maintaining a consistent temperature, the steel formwork effectively averts these detrimental cycles. Furthermore, steel formwork acts as a shield against chemical reactions that can contribute to spalling. Certain chemicals, such as sulfates or chlorides, have the potential to react with the concrete, causing its structure to deteriorate and spalling to occur.
