摘要: The Nernst–Planck equation describes ionic movements in saturated porous materials subject to chemical concentration gradients the pore fluid and applied electric fields. When a macroscopic system supposes that flux of each ion is independent every other one. However, owing exchange among different or similar species, there are potentials affect final flux. These will distort field thus keep electroneutrality sum all species involved. potential fall linearly across sample but an additional ‘membrane' change with position time. This paper summarises theoretical experimental investigation into application non-linear membrane simulation migration chlorides concrete. A new electrochemical test has been developed carried out samples concrete blended pulverised fuel ash (PFA) g...
