The simulation experiment and the similarity of chloride ion erosion in concrete under the tidal zone in the marine environment

摘要

To obtain the similarity relationship between the simulation experiment and the field experiment of chloride ion erosion in the concrete under the marine environment, on the basis of chloride ion ingress concrete under the onsite marine environment in Zhou Shan, a series of field corrosion tests involving the chloride ion ingression in the costal tidal zone are carried out. By simulating the environmental parameters of the tidal zone, the onsite environmental elements are simulated and modified in order to accelerate the ingress of chloride ion in the concrete. And the accelerated experiment is designed and completed. By comparing the results from the indoor accelerated experiment and the field test, the similarity of the main ingress parameters between the indoor and onsite durability experiment is analyzed.
