Abstract
The estimation functions were proposed for calculating diffusion coefficient, chloride binding, andevaporable water. The program estimating chloride ion penetration was developed on the basis of these functionsand the effects of humidity, curing temperature, water-cement ratio, and C3A on chloride penetration were analyzed.The relative humidity increases the depth of chloride ion penetration and the trend becomes greater with aging.On the contrary, the influence of curing temperature on chloride ion penetraton decreases with aging. By the way,the rise of C3A in cement increases total chloride concentration on the surface as the bound chloride concentra-tion increases but it decreases total chloride concentration on the inner part as the difusion velocity of frechloride decreases. The fal of water-cement ratio decreases the chloride penetration depth rapidly. Therefore, thereduction of water-cement ratio may be the most effective method for reducing of the stel corrosion by chloridepenetration.
