Abstract
The variants of using sphagnum in human economic activities are considered, including the technology of collecting and drying moss. The internal structure was studied with the help of light microscopy, the sizes of the parenchymal and hyaline cells of the leaf and the sphagnum stem were determined. The cellular structure of the moss stalk, with the dimensions of the cell membranes 6…45×50…80 μm at the thickness of the intercellular partitions 0.5…1.5 μm, exceeds the microstructure of expanded polystyrene by its parameters. The scanning tomography of the samples made it possible to estimate the external dimensions and surface of the moss stalk. The obtained data on the cellular microstructure and external characteristics provide the possibility of using moss as a natural aggregate for the manufacture of an effective heat-insulating material with bactericidal properties that is safe for the environment and human health.
