4 Common Cause of Scaling on Concrete Surfaces ETC Blog

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. Non- or Low-Air-Entrained Concrete – Air-entrained concrete ...

What Caused This Scaling? Concrete Construction Magazine

Jul 07, 2008  Simply using salt to melt ice and snow on concrete surfaces can exaggerate the effects of freezing and thawing. Applying salt to an ice-covered sidewalk leaves a liquid with a reduced freezing point. That gets down into the concrete and if the temperature drops far enough, that means the concrete goes through an additional freeze/thaw cycle.
