Abstract

Abstract

The specimens of concrete core with a diameter of 100mm were drilled from different elements of the dock in Qingdao Beihai Dockyard.The content of calcium carbonate in carbonation zone and chloride distribution from the specimens ware measured.The influence of materials and environments on carbonation and chloride distribution were analyzed.The test results show that the carbonation rate is slow in extremely humid environment,and the incomplete carbonation zone is dominant in carbonation zone,the depth of carbonation tends to a limit.The distribution of chloride ions is influenced evidently by local environment conditions,which can make the depth of convection zone changing widely.
- chloride ion,
- carbonation,
- apparent diffusion coefficient,
