Description
(54) СПОСОБ ПРИГОТОВЛЕНИЯ ПЕНОБЕТОННОЙ СМЕСИ Изобретение относитс к производству строительных материалов. Известен способ приготовлени пенобетонной смеси, включакиций приготовление технической пены, смешивание ее с цементным тестом, а затем добавление заполнител и дополнитель ное перемешивание смеси l . Наиболее близким к предлагаемому по технической сущности вл етс спо соб приготовлени пенобетонной смеси путем смешени гор чего (75-90 С) активированного цементного теста с холодными заполнителем, технической пеной и водой Г2 1. Недостаток известного способа - в сокий расход пенообразовател , невысока прочность. Цель изобретени - снижение расх да пенообразовател , снижение водопоглощени и повышение прочности. Поставленна цель достигаетс те что согласно способу приготовлени нобетонной смеси путем смешени технической пены, в жущего с водой и заполнителем с предварительным подогревом одного из компонентов, предварительно подогревают техническую пену до 30-70 С, а пенобетонную смесь разогревают острым паром до 40-80 с. Способ осуществл етс следующим образом. Из пенообразовател в циркул ционном пеногенераторе за 5 мин взбивают техническую пену npi одновременном подогреве T3HoMjTeMnepaTypa пены составл ет соответственно 30,50 и 70 С. Затем гор чую пену смешивают с холодг ным цементным тестом (соотношение во дагцемент составл ет 0,2) в течение 0,5 мин в смесителе. Затем в поризованное цементное тесто добавл ют керамзит и перемешивают смесь. Одновременно через специальные сопла в перемешиваемую смесь в течение 1,2 и 3 мин подают острый пар. Температура 3 смеси составл ет соответственно 60 и 80 С. АО, Свойства пенобетона приведены 8570624 в таблице.(54) METHOD FOR PREPARING A FOAM CONCRETE MIXTURE The invention relates to the production of building materials. There is a known method of preparing a foam concrete mixture, including the preparation of a technical foam, mixing it with cement paste, and then adding a filler and further mixing the mixture l. The closest to the proposed technical essence is the method of preparing the foam concrete mixture by mixing hot (75-90 ° C) activated cement dough with cold aggregate, technical foam and water G2 1. The disadvantage of this method is that low foaming agent consumption is low. The purpose of the invention is to reduce the consumption of foaming agent, reduce water absorption and increase strength. The goal is achieved by the fact that according to the method of preparing a concrete mix by mixing technical foam, which is in contact with water and aggregate with preheating one of the components, the technical foam is preheated to 30-70 ° C, and the foam concrete mixture is heated with hot steam to 40-80 s. The method is carried out as follows. From the frother in the circulating foam generator, for 5 minutes, beat the technical foam npi while simultaneously heating the T3HoMjTeMnepaTypa foam is respectively 30.50 and 70 C. Then the hot foam is mixed with the cold cement paste (the ratio to the dagcement is 0.2) for 0 5 min in the mixer. Then, expanded clay is added to porous cement paste and the mixture is stirred. At the same time, special steam is fed through special nozzles into the stirred mixture for 1.2 and 3 minutes. Temperature 3 of the mixture is 60 and 80 ° C, respectively. AO. The properties of the foam concrete are given in 8570624 in the table.
