The Study of Species Diversity of Fungi-Litaliano Allocated with Samples of Cement Composites Containing Limestones of Different Origin and Subjected to Aging at Conditions of the Black Sea Climate

Abstract

The article presents the results of a study of the decay resistance of cement composites filled with carbonate and silicate rocks. The investigated composites exhibited for one year under conditions of the black sea climate in the open air under a canopy of sea coast and sea water. Species and generic diversity of fungi-Litvinov on the samples, depending on the origin of carbonate rocks and the conditions of aging. By results of researches it is stated that fouling, the number of species in the community, as well as specific species composition to a greater extent depends on the operating conditions of the material, and to a lesser extent on the mineral composition of the filler. The authors give a classification of biological agents- destructors of building materials in their preferred conditions of growth that may be promising for the further development of approaches to deal with them. Installed rational compositions of concrete composites derived from limestones of different origin.
