Steam structure and thermal conductivity of lightweight concrete aggregate

Abstract

The article describes the results of theoretical and experimental studies to identify the relationship between the parameters of the steam structure and thermal conductivity of ashclaydite. The correlation dependences of the thermal conductivity coefficient of ash-claydite on its parameters of the stream structure have been established. The analysis of these works shows that the thermal conductivity of lightweight concrete depends on the type of porous aggregate, on the direction of the heat flow in relation to the layering of the concrete, the average temperature at which heat transfer occurs, the average density and moisture content of the concrete. In most works, a significant effect of the steam structure of the aggregate on the thermal conductivity of concrete is noted.
