Abstract

Analyzing fungus resistance of gypsum and organic composites is extremely important since fungi may both lead to deterioration in mechanical and operational properties of construction materials and adversely affect people’s health, including development of chronic diseases. We study fungus resistance and fungicidity characteristics of popular finishing gypsum and organic (epoxy- and polyester-based) composites. Plaster materials get exposed to micromycete biocorrosion faster than the ones based on a polymeric binding. Micromycetes adapt on plaster samples quicker than on epoxy and polyester samples. During their metabolism, micromycetes intensively allocate acid products on plaster samples, their high enzymatic activity is also noticed on polymeric materials.
