Laboratory degradation of building materials and structures


The laboratory is focused on studying the processes of degradation and changes in mechanical properties of building materials and components due to biological factors . The department is able to provide a wide range of analyzes to determine the type and activity of pests , extent of damage and the causes of its origin . Laboratory equipment allows identification and cultivation tests damaged building materials ( wood , stone, concrete, etc. ) with different types of microorganisms ( fungi) and organisms ( fungi, algae , lichens, etc. ) . In relation to other work centers of excellence , it is possible to monitor the impact effect on biodegradation properties of building materials.

Example output of the laboratory:

Processing wood sample taken from the component damaged by decay fungi ( rot ) - determine the gender classification of active wood-destroying fungi and their activities .

wood sample taken in the field of control activities damaged wood-destroying fungi

placement of grafts wood on sterile gel fertile ground - placed in an incubator - the beginning of cultivation

growth substrate and aerial mycelia of wood-destroying fungi during cultivation tests

microscopic evaluation - identification and generic classification of acting against fungi
