FIELD: building materials. SUBSTANCE: heated filler agent is treated with high molecular substance (polyvinilbutiral) in mixture with quartz sand. The mixture is treated under vibration. As a result of this treatment interface between the filler and mineral stone becomes larger. EFFECT: improved attachment, higher compression strength.

Изобретение относится к области строительства, к способам обработки заполнителя для тяжелых бетонов. Способ позволяет получать плотный заполнитель с прочной шероховатой поверхностью. Для этого нагретый заполнитель обрабатывают высокомолекулярным веществом (поливинилбутираль) в смеси с кварцевым песком и обработку ведут под воздействием вибрации.В результате такой обработки поверхность соприкосновения заполнителя с минеральным камнем становится больше, что улучшает сцепление и,следовательно,значительно повышает прочность тяжелого бетона на сжатие и растяжение.The invention relates to the field of construction, to methods for processing aggregate for heavy concrete. The method allows to obtain a dense aggregate with a strong rough surface. To do this, the heated aggregate is treated with a high molecular weight substance (polyvinyl butyral) in a mixture with quartz sand and the processing is carried out under the influence of vibration. As a result of this treatment, the contact surface of the aggregate with mineral stone becomes larger, which improves adhesion and, therefore, significantly increases the compressive strength of heavy concrete and sprain.
