Claims (1)

Способ получения арболита, включающий низкочастотную ультразвуковую обработку древесного заполнителя с последующим перемешиванием с минерализатором (раствором сульфата алюминия концентрацией 11%), вяжущим (портландцемент М500), формованием, распалубкой и твердением в естественных условиях, отличающийся тем, что в качестве древесного заполнителя используют фракционную смесь опилок и щепы, состоящую из 4 объемных долей щепы и 1 объемной доли опилок, которую на первой стадии получения арболита подвергают озвучиванию в воде в ультразвуковом реакторе контактного типа, стенки которого выполняют функции излучателей, что обеспечивает при времени озвучивания 20-30 мин повышение температуры до 70-80°С за счет кавитации с одновременным подкислением раствора до значения рН 5,1.A method of producing wood concrete, including low-frequency ultrasonic processing of wood filler, followed by mixing with a mineralizer (solution of aluminum sulfate with a concentration of 11%), binder (Portland cement M500), molding, stripping and hardening in natural conditions, characterized in that a fractional mixture is used as wood filler sawdust and chips, consisting of 4 volume fractions of chips and 1 volume fraction of sawdust, which, at the first stage of obtaining wood concrete, is subjected to sonication in water in a contact-type ultrasonic reactor, the walls of which serve as emitters, which provides, with a sonication time of 20-30 minutes, an increase in temperature to 70-80 ° C due to cavitation with simultaneous acidification of the solution to a pH of 5.1.
