Type of article: Periodical article

Summary

THEORETICAL ANALYSIS OF THE EFFECT OF THERMOMETRIC AND HYGROMETRIC PARAMETERS DURING THE COOLING STAGE ON TEMPERATURE DISTRIBUTION, HEAT DISCHARGE IN ATMOSPHERE, THE FORMATION AND DISTRIBUTION OF THERMAL STRESSES IN A CONCRETE ELEMENT DURING ITS COOLING. THE AA. CHECKED CONCRETE ELEMENTS SUBJECTED TO THERMAL TREATMENT WITH LOW PRESSURE STEAM. THEY SHOWED THAT THE BOUNDARY INTENSITY OF COOLING (20 K/H) IS NOT A SUFFICIENT CRITERION FOR PROTECTING CONCRETE AGAINST CRACKING. THEY PROPOSED A MODIFIED CYCLE FOR THE THERMAL TREATMENT OF CONCRETE, CONSISTING OF SHORT TERM INTERNAL HEATING AND LONG-TERM CONTROLLED COOLING. (Bull. anal.
