Method for Calculating the Durability of Bricklaying Materials Based on Chemical Corrosion Processes

Abstract

Estimation of the durability of building ceramics is an important applied task. Especially difficult is an analysis of multi-layer building enclosures because of potential interactions of their component parts. Durability of building ceramics is in need of additional research. In this article, the method of evaluation of chemical resistance of a ceramic brick is reviewed. The research was conducted to determine the error of the method with the use of sodium hydroxide as a destructive agent. The results have shown a minor standard deviation of 2.74% with a confidence interval of 3.11%. The comparative analysis of alkalis activity interacting with ceramic materials was conducted: an experiment with sodium hydroxide and potassium hydroxide were made and chemical degradation coefficients are included. The results has demonstrated different degree of alkali effect in the same experiment conditions that confirmed thermodynamic calculation of chemical reaction’s trends. The methods of corrosion research of building ceramics with use of calcium hydroxide and magnesium hydroxide were reviewed and completed and mass-spectrometric analysis of these solutions were conducted. Conducted analysis and completion of the research methods that evaluate degradation of building ceramics creating a vector for the following researches with a goal to create a broader picture of corrosion process of building materials.
