摘要

In view of the intrusion of seawater into concrete structures, a large number of harmful substances, especially chloride ions, can be brought in, which can significantly shorten the actual service life of concrete structures, resulting in serious waste of resources. In this paper, the chloride ion accelerated corrosion test on the concrete structure of road and bridge engineering is carried out to test the chloride ion concentration in different depths of concrete with special protection and without special protection at different corrosion times, and the effect of special protection is studied to study the diffusion coefficient and chloride ion concentration on the concrete surface of road and bridge engineering. The test results show that the diffusion coefficient of chloride ion in concrete can be reduced by 31.3% and the concentration of chloride ion on concrete surface can be reduced by 22.67% by special protective measures.
