| Title of the article | The problems of biodeterioration of mineral construction materials in model test |
| Abstract. | Biodeterioration problems are actual for all types of mineral construction materials. Biocorrosion is the process of destruction of materials occurring under the action of microorganisms, primarily fungi and their metabolic products – monobasic, dibasic, tribasic carboxylic acids and acid-base enzymes. Biological corrosion is a complicated and multistage process. The current theoretical generalization of biodeterioration processes of mineral materials do not allow describe the processes of biocorrosion necessary integrity. In this regard, we propose a method of studying the biocorrosion process of mineral construction materials in weak organic acid reaction substance, simulating the process of biological corrosion of mineral consrtruction materials, without the use of microorganisms. Comprehensive pH-metric and IR spectral analysis of interaction processes of model substances with cement-sand mortar was undertaken. The main parameters of the biological stability of samples of mineral construction materials was defined. This will permit to create a mathematical model of the process of biological damage of construction materials, allowing with the required accuracy to describe the process of biocorrosion of mineral construction materials in different substance and temperatures. |
