Specific features of the thermal treatment of cement in massive constructions with the surface module less than 2,0 M [-1] are discussed in the paper. On the basis of the conducted profound investigations there have been determined quantitative values of exothermic heat in the process of aquation of Belarussian cement. The determined interconnections betwween the heat emited and cement brand as well as the temperatures of concrete in the process of hardening are presented. The paper also focuses on non-admission of contingencies due to underestimation of exothermic heat and violations in heating technology. Examples of heating are also given

In modern conditions, due to development of new architectural forms and designs, application of light self-supporting enclosures (walls) of sports, cultural and residential purpose buildings and premises, a particular role is played by framed cast-in-place and prefabricated structures, being a framework of stable, bearing complex made of either cast-in-place of prefabricated elements (columns, bars, beams and floor slabs). When making cast-in-place structures in winter conditions, conventional widely used heating methods (i.e., electrode, infrared, induction, etc.) are limited significantly due to possible current fault to reinforcement rods, sectional heating of concrete and chemical deleterious effect on reinforcement.

V nastoacee vrema pomimo termosnyh metodov, v tom cisle s ispol’zovaniem protivomoroznyh i uskoraucih dobavok, uspesno primenautsa kontaktnye metody progreva betona. Odnim iz nih avlaetsa obogrev provolocnym metalliceskim provodom, sucnost’ kotorogo zaklucaetsa v obogreve takimi provodami, svezeulozennogo betona, kotorye pri propuskanii toka peredaut emu teplo. Kak pravilo, on primenaetsa dla skvoznogo i periferijnogo progreva betona v konstrukciah s gustym armirovaniem, a takze v stykah soedinenij zelezobetonnyh elementov.
