Control of Chemical Degradation of the Wall Ceramic Material, Taking into account the Parameters of the Construction Operation

Abstract

The article discusses a new method for estimating the rate of destruction of building ceramics material based on the process of chemical corrosion of the material. The authors have developed and described the chemistry of the destruction process, consisting of two stages - the stage of formation of alkali and alkaline earth metal hydroxides when moistening the building ceramics material and the stage of interaction of hydroxides with silicon and aluminum oxides of the amorphous part of the material. Methods for studying the kinetic characteristics of both stages of the material destruction process have been developed. Currently, the methods have the status of state standards. Based on the analysis of the research results, a phenomenological equation has been developed to calculate the rate of chemical destruction of building ceramics material. The developed method for evaluating the enclosing structure according to the most critical coordinates is given, taking into account the rate of chemical corrosion, the distribution of temperature and humidity over the thickness of the structure. Based on the mathematical model, a program for calculating the durability of wall ceramics has been created. The results of the work are important when monitoring the reliability of load-bearing structures. On the basis of the obtained mathematical model for determining the resistance of the wall ceramic material to chemical corrosion processes, it is possible to control the correct operation of buildings and structures.
