Determination of durability of building ceramics

Abstract

Introduction. Large-scale field studies of the destruction of brickwork carried out by the author in many regions of the world showed that the approach to the research of the durability of building ceramics based on the strength parameter and the frost resistance parameter are not indicative. These parameters do not make it possible to obtain a temporary value of the durability of the material, but are just the basis for an expert assessment.Materials and methods. This paper proves the scientific hypothesis put forward by the author that the destruction of brick material in the brickwork of enclosing structures occurs under the influence of chemical corrosion processes. The process of chemical corrosion is described, the results of thermodynamic calculations of chemical processes are briefly presented. A brief description of the methods of studying the durability of the building ceramics material, which have now received the status of standards, is given.Results. The results of laboratory studies of the process of chemical destruction of the building ceramics material, as well as calculations of the durability of the building ceramics material performed on the basis of the developed method of calculating the durability of the material are presented.Conclusions. Based on the developed theoretical justification and laboratory studies of the process of chemical destruction of the wall ceramics material, it is concluded that the created research methodology and calculation method allow to determine the durability of the material at any stage of its operation.
