Abstract

Abstract

The chloride ions'concentrations in ex isting concrete in tidal estuary environment of the Qiantang River are measured, the relation between erosion depths and concentrations of chloride ions in concrete is analyzed. Based on the samples, the porosities of existing concrete are measured, and the relations between control starting points and porosities is also studied. In addition, there is stronger randomness in distribution of chloride ions'concentration at the different depths of existing concrete.
- existing concrete,
- chloride ions,
- porosity,
- randomness
