Domestic expressway are exposed to damage of combined deterioration by excessive use of deicer and a lot of cost is required for maintaining damage structures. Therefore now is the time that durability of subsidiary concrete structures is required to enhanced in order to reduce maintenance cost of structures and to promote road safety.
In this study measured scaling resistance of concrete using the 4% CaCl2 used in the ASTM C 672 and 3% NaCl used in the MTO LS-412.
