Description

Известны способы о,бработки в бетономешалках бетонных смесей с пористыми заполнител ми.There are known methods for processing concrete mixes with porous aggregates in concrete mixers.

Описываемый способ отличаетс  от известных тем, что обработку бетонпой смеси производ т в смесительной машине путем окатывани  заполнител  (например, керамзита, шлаковых искусственной и естественной пемз, аглопорита, керамзитового щебн , перлита, ка-рагандита, туфа и др.) в сухом виде дл  истирани  с него излишне развитых поверхностей и закрыти  наружных пор. Затем смесь увлажн ют и перемешивают ее до полной обмазки зерен цементным клеем. При таком способе обработки достигаетс  повышение прочности бетона при уменьшении расхода цемента и объемного веса бетонных изделий.The described method differs from the known ones in that the treatment of the concrete mixture is carried out in a mixing machine by sanding the aggregate (for example, expanded clay, artificial and natural slag stone slag, agloporite, expanded clay, pearlite, pearlite, cargandite, tuff, etc.) in dry form for wipe over-developed surfaces from it and close the outer pores. The mixture is then moistened and stirred until the grains are completely covered with cement glue. With this method of processing, concrete strength can be increased by reducing the consumption of cement and the volume weight of concrete products.

В результате окатывани  получают округленные пористые зерна заполнител  и легкий гидравлически активный порошок. Последним обогащают цементный клей, заполн ющий пустоты между сближенными зернами заполнител . Затем смесь увлажн ют и перемешивают ее до полной обмазки зерен цементным клеем.Rounding results in rounded porous aggregate grains and light hydraulically active powder. The latter is enriched with cement glue that fills the voids between the approximate filler grains. The mixture is then moistened and stirred until the grains are completely covered with cement glue.

Таким образом, при обработке, например, керамзитобетона дл  крупных панелей достигаетс  экономи  цемента марки 400-500 в пределах 100-120 кг/м, снижаетс  объемный вес керамзитобетона на 20-25%, а так же отпадает необходимость в р де случаев примен ть дефицитные легкие пески.Thus, when processing, for example, expanded clay concrete for large panels, the cement of grade 400-500 is saved within 100-120 kg / m, the bulk weight of expanded clay concrete is reduced by 20-25%, and there is also no need to apply scarce light sands

Лабораторией технологии бетонов, крупных блоков и панелей НИИсельстро  Госстро  РСФСР описываемый способ обработки бетонной смеси одобрен и рекомендован к промышленному использованию.The laboratory of technology of concrete, large blocks and panels of the NIIselstro Gosstro RSFSR describes the method of processing concrete mixture approved and recommended for industrial use.

№ 149336- 2 Предмет изобретени No. 149336- 2 The subject invention

Способ обработки в смесительной машине бетонных смесей с пористыми заполнител ми, отличающийс  тем, что, с целью повышени  прочности бетона и снижени  объемного веса при уменьшенном расходе цемента и получени  цементного кле , обогаш;енного песчаными фракци ми заполнител , обработку бетонной смеси производ т путем окатывани  заполнител  в сухом виде дл  истирани  с него излишне развитых поверхностей, а затем смесь увлажн ют к перемеш ивают ее до полной обмазки зерен цементным клеем.A method for treating concrete mixes with porous aggregates in a mixing machine, characterized in that, in order to increase the strength of concrete and reduce the bulk density with a reduced consumption of cement and to obtain a cement glue, sand-filled aggregate, the concrete mix is produced by sanding place the filler in a dry form to rub out excessively developed surfaces from it, and then the mixture is moistened to mix it up until the grains are completely covered with cement glue.
