Scaling Concrete Surfaces

Scaling Concrete Surfaces Technical information prepared by Ohio Concrete SCALING: Scaling, as defined by ACI Committee 116R, is the ‘local flaking or peeling away of the near-surface portion of hardened con-crete or mortar’. It is primarily a physical action created by hy-draulic pressures from repeated cycles of water freezing within

Scaling Concrete Surfaces — What, why, how? – Nevada ...

Scaling is local flaking or peeling of a finished surface of hardened concrete as a result of exposure to freezing and thawing. Generally, it starts as localized small patches which later may merge and extend to expose large areas. Light scaling does not expose the coarse aggregate. Moderate scaling exposes the aggregate and may involve loss of ...

May 09, 2017  Scaling occurs when a thin layer of the concrete surface flakes, or scales, from the concrete element. Removal of this thin layer often exposes the underlying, open-pore structure of the concrete, which poses a durability concern. The most common causes of scaling are listed below.
