Abstract

The article is sacrificed to the aerated concrete building barriers moisture phenomenon. Water, which increases heat conductivity of building materials is the reason of the increased heat loses during the winter season. The result of this phenomenon is the decrease of indoor heat comfort parameters. Aerated concrete is a strongly water absorbing material with elongated time of water desorption. Capillary-porous structure of the described medium makes is highly prone to water influence what is the reason of the detailed analysis of heat conductivity coefficient in relation to moisture. In this article it is analyzed and compared the influence of moisture changes on heat parameters of the aerated concrete with the bulk densities of 400 and 600 kg/m3 using the reflectometric techniques TDR (Time Domain Reflectometry).
