Изобретение относитс  к производству строительных материалов и касаетс  способа обработки пористых заполнителей дл  бетона, заключающегос  в нанесении на его поверхность в жущего.The invention relates to the production of building materials and relates to a method for processing porous aggregates for concrete, consisting in applying to its surface on its surface.

В известном способе на поверхность заполнителей нанос т цементный клей, а затем в него втапливают песок, в результате чего на поверхности заполнителей образуетс  прочностна  оболочка.In a known method, cement glue is applied to the surface of the aggregates, and then sand is embedded in it, as a result of which a strength sheath is formed on the surface of the aggregates.

Недостатками известного способа  вл етс  недостаточное сцепление заполнител  с создаваемой прочностной оболочкой, а также значительна  потребность в в жущем.The disadvantages of this method are the lack of adhesion of the aggregate to the strength shell being created, as well as a significant need for a ghost.

Предлагаемое изобретение позвол ет повысить прочность заполнител , а также улучщить сцепление заполнител  с прочностной оболочкой и уменьщить количество в жущего на единицу продукции.The present invention allows to increase the strength of the aggregate, as well as to improve the adhesion of the aggregate to the strength sheath and reduce the number of stitches per unit of production.

Достигаетс  это тем, что пористые заполнители предварительно обрабатывают паром избыточного давлени  с температурой от 100 до 145°С.This is achieved by the fact that porous aggregates are pre-treated with overpressure steam with a temperature of from 100 to 145 ° C.

Обработанный паром заполнитель перемешивают в мещалках известного типа с в жущим в количестве 2-5% от общего количества в жущего, потребного дл  изготовлени  бетона. После чего в мещалку подают остальные компоненты бетонной смеси.The steam-treated aggregate is mixed in meshes of a known type with a holding in the amount of 2-5% of the total number of binding needed to make concrete. After that, the rest of the concrete mix is supplied to the broom.

При охлаждении пористого заполнител  в его порах будет конденсироватьс  пар и создаватьс  вакуум, в результате чего в жущее войдет в поры.When the porous aggregate is cooled, steam will condense in its pores and create a vacuum, with the result that the perch will enter the pores.

Следствием указанного  влени  будетThe consequence of this phenomenon will be

улучщение сцеплени  заполнител  с прочностной оболочкой и увеличение его прочности. Механическа  прочность керамзитового грави  и иеска, обработанных предлагаемым способом, увеличиваетс  в 5-6 раз.improving the adhesion of the aggregate with the strength sheath and increasing its strength. The mechanical strength of expanded clay gravel and sand processed by the proposed method increases 5-6 times.
