DESIGN AND CHOICE OF DURABILITY ASSESSMENT PARAMETER OF CONCRETE IN SALTY SOIL REGION

After designing rationally the assessment targets on concrete durability，the assessment parameters are used to show the durability deterioration course of concrete in sulfate environment. The results show that every performance deterioration degree of concrete can be compared on the same coordination axis by assessment parameters. The assessment parameters are applicable to the same determination criterion，and the determination principle is simple and convenient. The comparing of the deterioration course and sensitivity degree of concrete performance is much easy. If concrete performance of anti-sulfate erosion is tested at laboratory，the result assessment ought to be done by the two non-destructive test assessment parameters.
