Development of a method of protection of concrete floors of animal buildings from corrosion at the expense of using dry disinfectants

Concrete floors are most commonly used in animal housing. However, the specific environment of livestock buildings (moisture, urine, disinfectants) has a negative effect on concrete and leads to its corrosion. The influence chemical physical factors is reinforced by development microorganisms, which quickly adapt use as living environment. To reduce an aggressive floor, experimental mixture dry disinfectants was proposed. components disinfection have been selected taking into account safety for animals humans. TPD-MS method determine change composition concrete. study microstructure concrete, scanning electron microscopy used. Microbiological studies revealed bacteria A. Thiooxidans, S. aureus, E. coli, enteritidis, ?holeraesuis, C. Perfringen micromycetes genus Cladosporium, Fusariums, Aspergillus, contribute biological corrosion buildings. fact impact concentrated structure also established. As result carried out, it proved that exhibits antimicrobial properties varying degrees strains field isolates fungi isolated pig-breeding farm. It found when using proposed research room pigsty, relative humidity decreases 38.5 %; ammonia content – 46.2 hydrogen sulfide 57.8 microbial bodies 74.7 %, compared with control room. experimentally proven disinfecting hygroscopic promising farms.
