Study on concrete strength under seawater corrosive action

According to the accelerated corrosion test of common Portland and slag Portland cement simple, water cement ratio from 0.45 to 0.60, the regular pattern and reason on the strength variation to the time were researched. The results provide quantitative explain data of destructional state. Furthermore under the same condition, slag Portland cement concrete is better than common Portland cement on ability of seawater corrosion resistance. When the anti corrosion coefficient of sample is 0.8, the limit value 25 percent of strength loss is all the same to American ASTM standard.
