This paper describes the results of studies on the effects of different biological environments of corrosive materials from the cement matrix modified with additives pre-mix and post-mix. In studies, it has been shown that the content of polymer premix, which, in a relatively short period (six months), a significant effect on the ability of cement materials for the growth of microorganisms is 3%, and for epoxy resins can be 5% relative to the weight of cement. CaCO3 depositing in the pores of materials cement is associated with the mineralization of organic substances, including polymeric modifiers are mineralized cement mortars. The microstructure of the mortar contains significant amounts of secondary ettringite indicating bacteria in the environment and the sulphate corrosion mould materials cement.
