Prevent Scaling - Portland Cement Association

Scaling is defined as a general loss of surface mortar or mortar surrounding the coarse aggregate particles on a concrete surface. This problem is typically caused by the expansion of water due to freezing and thawing cycles and the use of deicing chemicals; however, properly specified, produced, finished, and cured quality concrete need not suffer this type of deterioration.
