It is relevant in the field of PCM research to study the influence of Arctic climatic conditions characterized by high temperature difference, humidity and intense solar radiation in the summer season on their properties. Also, a relevant task is to study the influence of bio-infestation on the structure and strength of PCM, since microorganisms use the binder composition as a source of life support. The paper presents comparisons of bending and tensile strength of hybrid PCMs, as well as their open porosity, after 1 year of natural exposure and samples exposed for 12 months, with preliminary biocontamination.
