In terms of corrosion conditions,the causes of rusting rates of reinforcing bars in concrete can be grouped as prerequisites,fundamental conditions,and subsidiary conditions.An analysis from the three aspects is made,showing how the independent and reciprocal effects are caused by factors of natural environment such as temporature,humidity,rain,wind,etc.An evaluation is made on thelinear polarizationmethod.It is suggested that the artificial environment can serve as an important means to study the corrosion...
