Recently, the concern on the deterioration of concrete pavement due to de-icing salts and its counter measurements has been increased. Especially, a scaling phenomenon of concrete 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 de-icing chemicals. This paper discusses the testing conditions of freezing-thawing and scaling resistance.
