Title of the articleApplication of model mediums for the biostability assessment of mineral construction materials
Abstract.Problem statement. The purpose of the study is to select the composition of the model medium for assessing the biostability of mineral construction materials. Results. The main results of the study are that experimentally justified and proposed the composition of the model medium (consisting of monobasic acetic, dibasic oxalic and tribasic citric acids) for modeling the processes of biodeterioration of mineral construction materials. The role of individual carboxylic acids in the modeling of biodeterioration processes of cement-sand mortars is estimated. Conclusions. The significance of the results obtained for the construction industry is that as a result of the studies carried out, the composition of the model environment for the assessment of the biostability of mineral construction materials was selected. Found that the presence of acetic acid in carboxylic acids model mixture should be minimized or completely eliminated by replacing it with another combination of carboxylic acids.
Keywords.cement-sand mortar, acetic acid, oxalic acid, citric acid, model medium of carboxylic acids.
