Use of thermal analysis for the detection of calcium oxalate in selected forms of plastering exposed to the effects of Serpula lacrymans

The article discusses the interaction of metabolic products a wood-destroying fungus dry rot species (Serpula lacrymans (Wulfen) P. Karst.) with commonly used lime mortar. Mortar samples in presented experiment were made mostly laboratory conditions so as to make it possible set input and determine initial properties examined samples. Matured mortar placed cultivation boxes growth Serpula exposed its action for predetermined period time. For comparison, taken “in situ” from real structures also subjected experiment. thermal analysis comparative measurement by infrared spectroscopy (FTIR). results infected compared obtained reference (control) carried out was focused on assessing presence calcium oxalate, which is secreted into surroundings mycelium during active growing lacrymans.
