Protection of building materials from biodeterioration
Introduction. The foci of biological damage can lead to destruction of building materials. The paper presents the results of an examination of samples of brickwork and cladding of an industrial building with traces of biological damage. Materials and methods. The contamination of materials was identified using the Koch method. The effectiveness of biocides was evaluated using the disk diffusion method, namely, its modification applied to identify the fungicidal activity by adding antiseptics to samples of damaged building materials, identifying the number of viable microorganisms in the material, processing damaged building structures and monitoring the microorganisms on their surfaces. Results. The number of viable microorganisms in the studied samples of building materials exceeded the acceptable value, which evidences the process of biodegradation. The resistance of isolated strains of fungi to biocides, that have various derivatives of isothiazolone as the main active ingredient, was determined. Conclusions. Sanatex, Macrosept, Rocima GT, Rocima 243, Neomid 440 Eco can be recommended for the disinfection treatment of biologically damaged building materials.
