Humidity in the walls from aerated concrete for conditions northeast Asia

Abstract

The influence of the characteristics of external finishing coatings on the humidity regime in walls made of aerated concrete grades D350-D500 for buildings located in the geographic subregion of Northeast Asia has been assessed. The temperature of the onset of condensation has been determined depending on the type of finishing layer. The amount of condensed moisture in the fence in winter is calculated. The humidity regime in the walls was compared for the conditions of the Russian cities of Khabarovsk and Vladivostok, as well as for cities located in China close to the border with Russia - Beijing and Harbin. It has been established that the humidity regime of walls made of aerated concrete grades D350-D500, for the considered cities of China, to a greater extent, in comparison with the considered cities of Russia, depends on the characteristics of the external finishing coating.
