Description
Известен способ раздельного бетонировани путем укладки сухих заполнителей в форму с последующим их уплотнением и введением жидкой фазы, однако этот способ не обеспечивает плотной укладки бетона.There is a known method of separate concreting by laying dry aggregates in a form with their subsequent compaction and the introduction of a liquid phase; however, this method does not ensure tight packing of concrete.
Предлагаемый способ устран ет этот недостаток за счет того, что в качестве жидкой фазы используют водный раствор в жущего вещества в виде цементного молока, что и обеспечивает плотную укладку бетона.The proposed method eliminates this disadvantage due to the fact that an aqueous solution of a binder in the form of cement milk is used as the liquid phase, which ensures the dense packing of concrete.
Способ раздельного бетонировани при формовании бетонных и железобетонных конструкций и изделий осуществл етс следующим образом.The method of separate concreting in the molding of concrete and reinforced concrete structures and products is carried out as follows.
Форму (опалубку) загружают заполнителем оптимального гранулометрического состава, включа песок различной дисперсности, затем производ т уплотнение заполнител различными способами при помощи объемного вибрировани с пригрузом или без него (глубинными или поверхностными вибраторами иThe form (formwork) is loaded with aggregate of optimal particle size distribution, including sand of different dispersity, then the aggregate is compacted in various ways using volumetric vibrations with or without a load (deep or surface vibrators and
т. д.). После этого в заполнитель, плотно упакованный в форме, ввод т водный раствор (шлам) в жущего вещества - цемента, гипса, извести или какого-либо другого в жущего со специальными разжил ающими добавками (например, сульфито-спиртова барда), обеспечивающими пониженную в зкость раствора. Дл лучщего заполнени раствором межзерновых пустот в заполнителе примен ют различные способы - нагнетание водного раствора , залив водного раствора с вибрированием и вакуумированием.etc.) After that, an aqueous solution (sludge) is added to the aggregate, tightly packed in a mold, into a cement, gypsum, lime, or some other mortar with special diluent additives (for example, sulphite-alcohol bard), which provide reduced solution viscosity. For a better filling with a solution of intergranular voids in the aggregate, various methods are used - injection of an aqueous solution, filling of an aqueous solution with vibrating and evacuating.
