APPRAISAL OF THERMOPHYSICAL PROPERTIES OF A CONCRETE DAM

This paper describes a study of thermophysical properties of concrete of dam hydroelectric power station. It is known, that heat conductivity the platinum's of hydroelectric power stations cannot be defined by an experimental way. Therefore we have put a task to estimate heat conductivity of a part of a dam of hydroelectric power station consisting from concrete. During construction of a dam of power station test from a concrete part frequently undertake. The tests have cylindrical, prismatic, cubic form with the which approximately identical with conditions of dams ic the constancy of a moisture, temperature etc is observed. Theoretical and experimental methods study heat conductivity concrete in the room temperature. Common of relative error of measuring heat conductivity under confidential probability α = 0,95 range 4.2%. These materials, when flowing out of the reactor vessel, may interact with the concrete of the reactor building thus introducing decomposition products of concrete into the original mixture. These decomposition products are mainly; SiO₂, FeO, MgO, CaO and AI₂O₃ in different amounts depending on the nature of the concretes which are considered.
