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 и доломит, дополнительно содержит кварцевый песок и 70%-ную уксусную кислоту, введенную в воду для увлажнения шихты, при следующем соотношении компонентов, мас.%: глина монтмориллонитовая 80,0-85,0; кварцевый песок 11,75-17,8; доломит 2,0-3,0; 70%-ная уксусная кислота, введенная в воду для увлажнения шихты, 0,2-0,25.The technical result is achieved in that the mixture for the production of porous aggregate containing montmorillonite clay and dolomite, additionally contains quartz sand and 70% acetic acid, introduced into the water to moisten the mixture, in the following ratio, wt.%: Montmorillonite clay 80, 0-85.0; silica sand 11.75-17.8; dolomite 2.0-3.0; 70% acetic acid introduced into the water to moisten the mixture, 0.2-0.25.

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

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 porous aggregate.

Компоненты сырьевой смеси дозируют в требуемых количествах. В воду, приготовленную для увлажнения сырьевой смеси при перемешивании, вводят 70%-ную уксусную кислоту, размолотый до порошкообразного состояния доломит и выдерживают в течение 20-30 мин. Кварцевый песок смешивают с глиной монтмориллонитовой, смесь увлажняют до 20-26% приготовленной смесью воды, 70%-ной уксусной кислоты и доломита. Из шихты формуют гранулы размером 20-40 мм, которые сушат до влажности не более 6%, и обжигают при температуре 1000-1050°С.The components of the raw mix are dosed in the required quantities. 70% acetic acid, dolomite, milled to a powdery state, is introduced into the water prepared to moisten the raw material mixture with stirring and kept for 20-30 minutes. Quartz sand is mixed with montmorillonite clay, the mixture is moistened with 20-26% of the prepared mixture of water, 70% acetic acid and dolomite. Granules with a size of 20-40 mm are formed from the charge, which are dried to a moisture content of not more than 6%, and fired at a temperature of 1000-1050 ° C.
