The main maintenance of a determination of strength and thermal properties of lightweight concrete on the basis of local raw materials by the Republic of Tajikistan constant linear heat source. The dependence of the thermal conductivity of wet concrete on its temperature as a linear function , differentiated by zones of positive and negative temperatures, which is the basis for calculating the probability of heat engineering structures using the test light concrete .

The main maintenance of a  results of calculation of a thermointense condition of beams depending on various ways of an attachment to the basis - jammed in the basis, with absolutely hard sealing-off on end faces and absence of any communications at end faces is considered. The analysis shows, that the more age of "blocks-communications", the more they possess rigidity. It means, that they are less pliable, and sizes of pressure in the settlement block are close to pressure in the block with the jammed end faces.
