A comprehensive study on scaling resistance of concrete exposed to deicing chemicals was examined. In Japan, the spreading amount of deicing salts has been increasing in recent years and the research is backward. The temperature conditions specified in ASTM C 672 were tentatively controlled automatically, and the scaling resistance was evaluated by not only visual rating but also measurement of the mass of scaled-off particles on many types of concrete specimens, in the variety of testing surface such as top, side and bottom surfaces, air content, water cement ratio, curing condition, deicing salts and in the application of a permeable sheet enable to make dense the surface layer of concrete. Besides, the assessment of scaling damage of concrete was attempted non-destructively from a side view of both strength and permeability
