Recently many studies progressing due to the growing interest in the chloride damage. But most of the existing studies were about internal salinity when the concrete mixed, so its short of many studies about exterior salinity now. Accordingly this study analyzed for the prevention of chloride damage through measuring the absorption velocity of saturated chloride water, based on the types of surface finishing. The results derived in this study are as flow.
(1) The average absorption velocity of saturated chloride water according to exposure method, such as faster in the dry and wet cycled method than continuous exposure method. Also, the case of soak faster than the case of spray. (2) In the case of soak, the mixed type was proven to be most effective at chloride damage through measuring the average absorption velocity(4.5mg/g?hr) of saturated chloride water according to concrete surface finishing method. (3) In the case of spray, average absorption velocity(0.012mg/g?hr) of the water paint type was shown to be the lowest. (4) The average absorption velocity of the motar type measured to be the faster than all of types. Accordingly, motar type estimated that damage likely to be the most serious because of it had the lowest resistibility at all conditions of the dry-wet cycled method and continuous exposure method. (5) Accordingly, the mixed type and the water paint type was shown to be the most effective in all of types.
