Experimental Study on the Erosion Effect of Seawater on Bridge Foundation

Based on the mechanism of seawater corrodes concrete, the comprehensive and comparative analysis on the different anticorrosive methods was carried out. The several groups of samples were produced by adding new additive on the basis of concrete mix design in the laboratory. The erosion environments with the different corrosive ions were simulated. The mechanical nature and permeation heights of the pieces under the different erosion environments were studied. The study provides a reference for the durability design of concrete in the seawater.
