Изобретение может примен тьс  при строительстве монолитных бетонных и железобетонных сооружений, а также при изготовлении сборных бетонных и железобетонных изделий.The invention can be applied in the construction of monolithic concrete and reinforced concrete structures, as well as in the manufacture of precast concrete and reinforced concrete products.

Известен способ обработки бетонной смеси, заключающийс  в воздействии на нее посто нного тока переменной пол рности в течение 15-25 мин, благодар  чему смесь разогреваетс  до температуры 70-90-С.A known method of treating a concrete mix involves exposing it to direct current of alternating polarity for 15-25 minutes, thereby heating the mixture to a temperature of 70-90 ° C.

При прохождении посто нного тока переменной пол рности через бетонные и растворные смеси нар ду с выделением тепла происход т электроосмотические колебани  жидкой фазы смесей, которые позвол ют сн ть новообразовани , концептрирующиес  вокруг переменного зерна и преп тствующие дальнейшему его растворению.With the passage of direct current of alternating polarity through concrete and mortar mixes, along with the release of heat, electroosmotic oscillations of the liquid phase of the mixtures occur, which make it possible to remove tumors that are conceptualized around the variable grain and prevent its further dissolution.

При этом толщина окружающей цементное зерно пленки уменьшаетс  и создаютс  благопри тные услови  дл  гидратации цемента.In this case, the thickness of the film surrounding the cement grain is reduced and favorable conditions are created for the hydration of the cement.

1Делью изобретени   зл етс создание лучших условий дл  наиболее полной гидратации в  ку1цего и ускорени-г твердени  бетона при низких положительных и отрицательных температурах наружного воздуха.1The invention of the invention creates the best conditions for the most complete hydration and acceleration of concrete at low positive and negative outdoor temperatures.

Это достигаетс  толг, что на смесь воздействуют одновременно переменным током промышленной частоты В течение 3-20 мин. При совместном воздействии посто нного тока пс ремеппой пол рности /ПТПП/ и перемен)югоThis is achieved by saying that the mixture is simultaneously affected by an alternating current of industrial frequency for 3-20 minutes. With the joint effect of direct current ps polaros polarity / PTPP / and changes) south

тока промышленной частоты /ПТПЧ/ происходит нагрев бетонной смеси п микровибраци  жидкой фазы бетонной смеси, за счет которой нленка новообразований разрушаетс , что способствует более глубокому и полно.му протеканию процесса гидратации це: 1ентного зерна. Одновре.меппое совместное действие ПТПЧ и ПТПП приводит к более интенсивному ускорению твердени  бетона по сравнению с электроразогревом бетонной смеси отдельно ПТПЧ и ПТПП.current of industrial frequency (PFCF) / heats the concrete mix and microvibration of the liquid phase of the concrete mix, due to which the tumor of new growths is destroyed, which contributes to a deeper and fuller flow of the hydration process of the grain: 1 grain. Simultaneously, the joint action of the FSTP and the PTPP leads to a more intensive acceleration of the hardening of the concrete as compared with the electric heating of the concrete mixture separately PTPCh and PTPP.

Способ осуществл ют следующим образом. Бетоппую смесь загружают в .металл1гческнй бункер, внутри которого укреплена па изол торах металлическа  пластина. Па корпус бункера и пластину подают напр жение ПТПЧ 11 ПТПП с периодом перемены пол рьссти от 5 до 120 сек,. Обработку смеси ведут В течение 3-20 .I.UH.The method is carried out as follows. The Beethope mixture is loaded into a metal hopper, inside of which a metal plate is fixed to the insulators. The hopper case and the plate supply the voltage of the PTSHP 11 PTPP with a period of reversal of the range from 5 to 120 s. Processing the mixture are within 3-20 .I.UH.

Ксследозапн  показали, что в ранние сроки твердени  прочность образцов из бетонной смеси, обработанной созместпым действием ПТПЧ п ПТПП, выше на 10-20% прочности образцов из смеси, разогретой ПТПП.Ksledozapn showed that in the early periods of hardening, the strength of samples from a concrete mixture treated with the combined effect of PTPP and PTPP is 10-20% higher than the strength of samples from a mixture heated by PTPP.
