Predicting the residual life of concrete structures in biocorrosion from the position of the theory of mass transfer

The problem of corrosive destruction concrete and reinforced structures industrial buildings affected by aggressive environments does not lose its relevance, because, despite the abundance modern methods protection, there are still no radical corrosion control. Corrosive building materials leads to a strength load-bearing capacity reduction, loss aesthetic properties and, consequently, decrease in residual life structures. biological factor often acts as an intensifier destruction. In this regard, it is reasonable search for possibility predicting durability liquid mediums, taking into account biofactor effect from standpoint mass transfer theory. authors present model structure exposed environment biofouling. proposed physical mathematical considers environment, well kinetics continuous processes growth, reproduction death microorganisms. results numerical experiments on provided. application received solutions will allow timely monitoring biocorrosive selecting effective protection.
