Electrical resistivity of the material can be closely related to the coefficient of diffusion of chloride ions ingress [1], which is one of the crucial parameters needed for assessment and predictions of the length of service life of reinforced/pre-stressed civil engineering/transportation structures exposed to de-icing agents or marine environment.
Durability of such structures presents very important engineering topic nowadays.

Civil engineer would sweep through, changing the entire landscape of the site, which often damages the ecology of the environment.
From the structure of AHP for mountain road construction project, we have compared traditional engineering method with ecological engineering method.
Odum[4] first suggested the term ecological engineering.
Today, ecological engineering has been widely spread.
