Description

Изобретение относится к производству пористых заполнителей для бетонов.The invention relates to the production of porous aggregates for concrete.

Известна шихта для производства пористого заполнителя, содержащая, мас.%: глина монтмориллонитовая 35,0-38,0; уголь 5,0-6,0; доломит 36,0-50,0 [1].A known mixture for the production of porous aggregate, containing, wt.%: Clay montmorillonite 35,0-38,0; coal 5.0-6.0; dolomite 36.0-50.0 [1].

Задачей изобретения является повышение прочности пористого заполнителя, полученного из шихты.The objective of the invention is to increase the strength of the porous aggregate obtained from the mixture.

Технический результат достигается тем, что шихта для производства пористого заполнителя, содержащая глину монтмориллонитовую, уголь, доломит, дополнительно содержит фосфорный шлак при следующем соотношении компонентов, мас.%: глина монтмориллонитовая 79,0-80,0; уголь 2,0-3,0; доломит 5,0-9,0; фосфорный шлак 9,0-13,0.The technical result is achieved in that the mixture for the production of porous aggregate containing montmorillonite clay, coal, dolomite, additionally contains phosphoric slag in the following ratio of components, wt.%: Montmorillonite clay 79.0-80.0; coal 2.0-3.0; dolomite 5.0-9.0; phosphoric slag 9.0-13.0.

В таблице приведены составы шихты для производства пористого заполнителя.The table shows the composition of the mixture for the production of porous aggregate.

Фосфорный шлак содержит 90-95% стеклофазы и характеризуется следующим химическим составом, мас.%: SiO2 40,0-43,0; Al2O3 1,0-3,0; Fe2O3 0,4-1,0; CaO 42,0-49,0; MgO 3,0-4,0; SO3 2,0-3,0; P2O5 0,9-3,0.Phosphorus slag contains 90-95% glass phase and is characterized by the following chemical composition, wt.%: SiO 2 40,0-43,0; Al 2 O 3 1.0-3.0; Fe 2 O 3 0.4-1.0; CaO 42.0-49.0; MgO 3.0-4.0; SO 3 2.0-3.0; P 2 O 5 0.9-3.0.

В составе шихты для производства пористого заполнителя используют глины монтмориллонитовые, включающие Al-монтмориллонит и Fe-монтмориллонит (нонтронит).Montmorillonite clays, including Al-montmorillonite and Fe-montmorillonite (nontronite) are used in the mixture for the production of a porous aggregate.

Доломит содержит, мас.%: Al2O3 1,99; Fe2O3 0,12; CaO 29,88; MgO 20,04; K2O 0,27; п.п.п. 44,0.Dolomite contains, wt.%: Al 2 O 3 1,99; Fe 2 O 3 0.12; CaO 29.88; MgO 20.04; K 2 O 0.27; p.p.p. 44.0.

Компоненты сырьевой смеси дозируют в требуемых количествах. Уголь, доломит, фосфорный шлак размалывают до прохождения через сетку №014, добавляют молотую глину монтмориллонитовую и смешивают. Полученную шихту увлажняют до 18-24% и формируют из нее гранулы размером 20-40 мм, которые сушат и обжигают при температуре 950-1050°С.The components of the raw mix are dosed in the required quantities. Coal, dolomite, phosphoric slag are ground before passing through mesh No. 014, ground montmorillonite clay is added and mixed. The resulting mixture is moistened to 18-24% and granules of 20-40 mm in size are formed from it, which are dried and calcined at a temperature of 950-1050 ° C.
