PREDICTING CHLORIDE LEVELS IN MARINE CONCRETE
The durability of reinforced concrete structures in the marine environment is primarily dependent on chloride ingress through th cover concrete protecting the reinforcement. Predictions of durability can be made by defining the material, assessing the environmental conditions, and monitoring the durability performan of the material in that environment. Reliable predictions of chlo ingress into concrete therefore require early-age chloride-resist testing, a rational system of classifying the marine environment long-term monitoring of durability performance. The development o empirical chloride prediction model is discussed and long-term validations with results from structures considered. The model ha the advantage that it makes allowance for construction effects, concrete types and different marine exposure conditions. For the covering abstract see ITRD E117314.
