Известен способ изготовлени газобетона путем электропрогрева свежеуложенной газобетонной смеси.A known method of manufacturing aerated concrete by electrically heating a freshly laid aerated concrete mixture.
Целью изобретени вл етс улучшение структуры и физико-технических свойств бетона .The aim of the invention is to improve the structure and physico-technical properties of concrete.
Это достигаетс тем, что смесь разогревают со скоростью 5-12 град/мин до температуры 50-65°С, прерывают электропрогрев в момент интенсивного газовыделени , а по окончании вспучивани и отвердевани осуществл ют последующий электроразогрев со скоростью 4-10 град/мин до температуры изотермической выдержки.This is achieved by heating the mixture at a rate of 5-12 degrees / min to a temperature of 50-65 ° C, interrupting electrical heating at the time of intense gassing, and after the end of the swelling and hardening, the subsequent electrical heating is performed at a rate of 4-10 degrees / min to temperature isothermal exposure.
Сущность способа заключаетс в следующем .The essence of the method is as follows.
Приготовленную холодную газобетонную смесь заливают в формы, например, кассетного типа и разогревают смесь путем пропускани через нее электрического тока при помощи электродов, роль которых могут выполн ть , например, металлические стенки кассеты . Использу понижающий трансформатор, например, с выходным напр жением 110 в, смесь разогревают со скоростью 5- 12 гра(9/л«ын до температуры 50-65°С, котора соответствует температуре вспучивани . В момент интенсивного газовыделени , когда смесьThe prepared cold aerated concrete mixture is poured into molds, for example, of a cassette type, and the mixture is heated by passing an electric current through it using electrodes, the role of which can be performed, for example, by the metal walls of the cassette. Using a step-down transformer, for example, with an output voltage of 110 V, the mixture is heated at a speed of 5 to 12 gras (9 / liter) to a temperature of 50-65 ° C, which corresponds to the swelling temperature. At the moment of intense outgassing, when the mixture
вспучитс до заполнени объема формы на 2/3 от ее полного объема, электропрогрев прерывают. Таким образом, окончание вспучивани происходит без воздействи электрического тока на смесь. При таком режиме газоудерживающа способность смеси повыщаетс , а пористость формируетс , распредел сь равномерно.swell up to fill the volume of the form by 2/3 of its full volume, the electrical heating is interrupted. Thus, the end of the swelling occurs without the influence of an electric current on the mixture. In this mode, the gas-holding capacity of the mixture increases, and the porosity is formed, evenly distributed.
По окончании вспучивани и отвердевани осуществл ют последующий электроразогрев со скоростью 4-10 град/мин до температуры изотермической выдержки (90-100°С). При этой температуре издели выдерживают до набора заданной прочности.At the end of the expansion and solidification, the subsequent electrical heating is carried out at a rate of 4-10 K / min to an isothermal holding temperature (90-100 ° C). At this temperature, the product is kept to a set of specified strength.
