Membrane continued impedance

Surface Barriers The application of an overlay of low-slump concrete, latex-modified concrete (EMC), high-density concrete, polymer concrete, or bituminous concrete with membrane on the existing concrete provides a barrier that impedes continued intrusion of chloride anions, moisture, and oxygen that are necessary for continued corrosion. These barrier systems may be used only after decontamination because corrosive agents get trapped in the concrete, leading to loss in its capacity to function properly. [Pg.231]

It is worth noting that in this graph you can see that one of the polyethylene separators maintains high impedance even when temperature continues to increase, while the impedance for the other one falls off quickly after an initial spike, indicating a rupture of the membrane. The difference between these two different behavior characteristics depends on a complex combination of factors such as pore size, pore structure, and molecular weight of the polymer. [Pg.17]
