Experiments on the production of durable concrete, which makes it possible to build more efficiently in conditions of low temperatures in the Arctic and the Far North of Russia, are conducted at the Tomsk State University of Architecture and Civil Engineering.
"We do forced heating of concrete with the help of electricity, put the mortar in the formwork and take it out in the cold. For more than a day, the air temperature was about -30 ℃, but thanks to the foam insulation, the solution retained a positive temperature when solidified. Thanks to this, concrete does not freeze over, gains strength and other performance characteristics, " the press service of the university quotes the words of one of the participants in the experiment.
