Abstract: Da’an city in Jilin province is not only frost soil region in the north-east，but also is one of the most serious region where has salinization soil． In the soil the dissolved salt component HCO3 － ( CO2 － 3 ) and Na + content is the most，followed by Cl － and SO2 － 4 ，and there are small amounts of Mg2 + ，Ca2 + ，K + ，etc． In order to study the influence on the durability of concrete by the different soluble salts after the action of freezing-thawing cycles， separate salt and freezing-thawing cycle comparing tests of the concrete were conducted on the basis of the previous experimental study on the durability of concrete affected by double factors of the composite salts and freezing-thawing cycles． The characteristics and laws of the damage to concrete by corrosion due to sulfate，chloride and bicarbonate under the action of freezing-thawing alternation were summarized，and the mechanism of failure was analyzed further．
