Aiming at the corrosion problem of concrete in saline soil area of Qarhan Salt Lake in Qinghai Province, by measuring the dynamic elastic modulus and compressive strength of ordinary concrete and high performance concrete (HPC) exposed for 8 years, the relationship between compressive strength, water-binder ratio, corrosion resistance coefficient and relative dynamic elastic modulus was studied, and the binary correlation analysis was carried out with the slag content. Finally, the correlation between carbonation depth and compressive strength was analyzed. The results show that the corrosion resistance decreases with the decrease of compressive strength in bittern environment. The critical value of relative dynamic elastic modulus for HPC corrosion damage is 0.8, which is not 0.6 as thought by traditional theory. The water-binder ratio is lower than 0.33, the slag content is more than 26%, and the carbonation depth is controlled below 20mm, which can ensure HPC's high brine corrosion resistance.
