Increased requirements for heat insulation of building enclosure contribute to widening of modern effective building materials. One of those items is large-block hollow ceramics. Large-block hollow ceramics is actively used for building enclosure because of high properties and increasing production. However, it’s usage in outer walls and material’s humidification significantly decreases the durability of ceramic blocks. This article is about durability of large-block hollow ceramics. The main scientific hypothesis is that the web’s material of the block has increased chemical destruction speed compared to shell’s material. Also, article include the results of laboratory experiments of material’s destruction based on the process of material’s chemical corrosion that were conducted by developed methods of determination the corrosive activity of moisture and material’s chemical durability. Based on the results of pilot researches at one of Russian factories, the method of large-block ceramic material’s research was developed. The first stage results of research are shown. The results of research confirms the decrease of web’s material strength compared to strength of shell’s material.
