Comparative analysis of the complex of thermal and moisture properties of cement and lime plaster mortars

Based on the tests, thermal quality indices (TQIs) of plasters were obtained: cement plaster — 0.05 1/%, lime plaster — 0.03 1/%. A comparative analysis of the complex of thermal and moisture properties of cement and lime plaster mortars made it possible to establish the regularity of the effect of humidity on the thermal conductivity of these materials. The relatively lower TQI value of lime plaster is due to a lower increment in thermal conductivity from humidity. The results obtained confirm the need to put into practice plaster mortars with increased thermal and moisture properties and increase the accuracy of thermal calculations
