内容記述 |
The chloride attack on concrete structures in the atmospheric marine environment depends on the mechanism of aerosol chloride particles which are transported to the structural members. Many literatures expressed the level of severity on chloride attack based on the available aerosol chloride content at a certain location. The amount of aerosol chloride particles decreases with distance from seashore under the exponential equation. The proposals of severity were also referred to this empirical trend. However, this model is proposed a mechanism to against former conclusion by clarifying the statement of ‘Not overall aerosol chloride can be penetrated into concrete’. This means that the total amount of absorbed aerosol chloride ions is not equaled to the total chloride ions in concrete. This model is explained about the limitation of aerosol chloride ions penetration due to the saturated degree of moisture which is able to transport in concrete in a period of time. During a big typhoon, a lot of aerosol chlorides particles are transported to the concrete surface, however this phenomenon can also result the surface soaking from too much aerosol chloride ions on the surface. Whenever, concrete can not absorb total water on the surface, the surface is saturated and droplets will be formed. A location where is located very near to seashore, might have a surface soaking many times in a year. A structure near seashore might be very severe for chloride attack, but the severity is also limited by the environmental itself. This phenomenon can be thought as similar as the effect of rain-induced surface chloride dissolution. |
