Paper Title:
The Tests and Measures of Concrete Ageing and Steel Bar Corrosion of the Salt Free Contaminated Inland Waterlocks
  Abstract

There are mainly three phenomena, i.e. cracks, infiltration and denuding for judging the aging and defects from hydraulic concrete constructions. The inland waterlocks’ concrete ageing with salt free contamination are found basically the concrete denuding, rebar erosive expansion cracks and concrete surface gravel exposure and freeze thawing peeling-off as well occasionally. The severe aging phenomena always occur in some small structures in work bridges, sub work bridges, railway bridges and concrete waterlocks etc, especially in boundary beams or flange plates of the said beams. The result manifests that the test result is completely in conformity with the actual situation in the test of internal concrete steel bar erosion by means of Eigenvalue K method and half-cell potential method. In order to prevent steel bars in the concrete from eroding and guarantee the durability of waterlocks, currently the treating method used most frequently is the waterlock concrete surface carbonization resistance treatment
