So the SCF values should increase gradually with increasing even if the stress distributions are absolutely similar for different . Considering only the decrease of tension area of steel bar with increasing , the corrected SCF values can be obtained based on the SCF value for . It can be seen that the corrected values are smaller than the calculated values, which indicates that the stress distributions become more uneven with increasing . The conclusion conforms with the stress distributions in Figure 7. Steel reinforcement in RC structures is generally protected by a passive film formed in the alkaline environment due to the hydration products of cement . However, the protective film can be destroyed by attack of aggressive ions such as chloride and carbon dioxide .<\/p>\n
