Abstract
Large-block porous ceramics, which enter the market of building materials, have a number of undeniable qualities: low thermal conductivity, low density, high aesthetic qualities. According to its design features, this material is a modern prototype of hollow bricks used in construction since the nineteenth century. Field studies of the work of enclosing structures using hollow bricks have shown that in many cases, the bricks laid in the enclosing structures of buildings 60-80 years ago were significantly destroyed. In this case, the destruction mechanism does not depend on the polythermal load on the material. The hypothesis that the destruction is associated with the chemical destruction of the material was investigated using the developed method for determining the chemical resistance of the material of wall ceramics. The conducted studies confirmed the hypothesis. Studies of the chemical resistance of the material of large-block porous ceramics should be taken into account in the production technology of ceramics.
