The Analysis of Heat-and-moisture Conditions of Using Double-Layer Wall Panels

AbstractThe paper presents the calculation results of double-layer supporting walls and outer self-supporting walls made of expanded-clay lightweight concrete panels. The self-supporting layer is made of expanded-clay lightweight concrete (its density at least 1200kg/m3), the thermal insulation layer is made of no-fine expanded-clay lightweight concrete (its density 300-350kg/m3) supported by a textured layer made of cement and sand grout. The authors used their own method of non-dimensional characteristic while calculating moisture conditions of the wall. The method is supported by “Diffusion-2005” software system. Different construction areas in Russia were examined during the research. The calculations yielded the following results: there has been no moisture conservation in double-layer wall panels within a whole year of their operating life-time. The authors conclude that double-layer wall panels used while construction will cut the time of construction and increase their operating life-time and ecological compatibility
