Biodeterioration of Building Materials

Problems of bio-deterioration are actual for all types of building materials. Bio-corrosion is the process of materials destruction under the effect of micro-organisms, first of all, mould fungi and products of their metabolism – one, two, tribasic carboxylic acids. Existing methods of the study of bio-deteriorated building materials with the use of micro-organism strains are very complicated and labor-intensive. In this regard, to investigate processes of bio-deterioration of building materials the method for simulating processes of bio-corrosion in slightly aggressive media of organic acids is proposed. The kinetic laboratory unit which makes it possible to simulate the process of bio-deterioration of polymeric and mineral building materials, has been developed. Experimental studies of physical-chemical characteristics of epoxy polymers were conducted. Main parameters of bio-stability of mineral building materials samples have been defined. It is shown that one of prospective methods for protection of mineral building materials against the effect of biologically active media is the use of epoxy-polymeric coatings.
