Long-term performance of reinforced concrete under a de-icing road environment

In the middle of 1990, over 30 different mixes concretes with eight binders and water-binder ratios 0.3 to 0.75 were exposed a highway environment heavy de-icing salt spread for examination long-term performance, including chloride penetration, reinforcement corrosion frost attack. This paper presents results from this study regarding penetration corrosion. The show that in under road is much weaker than marine splash Sweden. estimated critical content initiation about % by mass binder rebars uncracked concrete cover. Considering redistribution surface zone, ClinConc model has been modified so it can present better description profiles at such an exposure site.
