Note: in this table, the steel with initial polished surface was marked as P. The w/c ratio of specimen was marked 70. The chloride content (wt% of cement) of specimen was marked as 0 and 3. The serial number of specimens was marked as 19, 20, 27, and 28. For example of P70-0-27, P means the steel had polished surface, 70 means the w/c ratio of specimen was 0.70, 0 means the chloride content of specimen was 0 wt% of cement, and 27 means the serial number of specimens was 27. Cycle types were marked as D, P, Q, R, S, and T, which was illustrated in Figure 2.
