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