Overview of the presence of predominant microorganisms on the interface of cementitious materials and soil from selected locations

The presented work focuses on the predominant microorganisms on the interface of cementitious materials and soils from different localities. Soils contain microorganisms that can affect the underground concrete structure positively or negatively. Different types of microorganisms are adapted to the environmental conditions depending on the quality and quantity of elements in the soil. Methodology of the work was based on screening 5 selected localities in the Košice city from which soil was taken in the nearness and in the contact with the concrete structure. These samples were further analysed. In this paper the presence of bacteria in the soil around the construction is confirmed.
