Description

Изобретение относится к составам сырьевых смесей, которые могут быть использованы для изготовления пористого заполнителя для бетонов.The invention relates to compositions of raw mixtures that can be used for the manufacture of porous aggregate for concrete.

Известна сырьевая смесь для изготовления пористого заполнителя, содержащая, мас.%: глинистое сырье 63,0-65,0; кианит 14,0-15,0 и другие компоненты [1].Known raw mix for the manufacture of porous filler, containing, wt.%: Clay raw materials 63.0-65.0; kyanite 14.0-15.0 and other components [1].

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

Технический результат достигается тем, что сырьевая смесь для изготовления пористого заполнителя, включающая глинистое сырье, кианит, дополнительно включает золу-унос, а в качестве глинистого сырья - глину монтмориллонитовую и каолин, причем компоненты находятся при следующем соотношении, мас.%: глина монтмориллонитовая 72,0-74,0; каолин 3,0-5,0; кианит 8,0-10,0; зола-унос 13,0-15,0.The technical result is achieved in that the raw material mixture for the manufacture of a porous filler, including clay raw materials, kyanite, additionally includes fly ash, and as clay raw materials montmorillonite clay and kaolin, the components being in the following ratio, wt.%: Montmorillonite clay 72 0-74.0; kaolin 3.0-5.0; kyanite 8.0-10.0; fly ash 13.0-15.0.

В таблице приведены составы сырьевой смеси для изготовления пористого заполнителя.The table below shows the composition of the raw mix for the manufacture of porous aggregate.

В качестве глинистого сырья в составе шихты для производства пористого заполнителя используют глины монтмориллонитовые, включающие Al-монтмориллонит и Fe-монтмориллонит (нонтронит). Используют кианит (дистен) - минерал из класса силикатов (Al2 SiO5), в котором возможна изоморфная примесь Fe2O3 до 7 мас.%.Montmorillonite clays, including Al-montmorillonite and Fe-montmorillonite (nontronite) are used as clay raw materials in the mixture for the production of a porous aggregate. Kyanite (distene) is used - a mineral from the class of silicates (Al 2 SiO 5 ), in which an isomorphic admixture of Fe 2 O 3 up to 7 wt.% Is possible.

Компоненты дозируют в требуемых количествах. Кианит измельчают до порошкообразного состояния, смешивают с золой-уносом, добавляют глину монтмориллонитовую, каолин и еще раз смешивают. Из полученной сырьевой смеси с влажностью 18-26% формуют гранулы, которые сушат до влажности не более 7% и обжигают при температуре 1050-1150°C.The components are dosed in the required amounts. Kyanite is crushed to a powder state, mixed with fly ash, montmorillonite clay, kaolin are added and mixed again. From the obtained raw material mixture with a moisture content of 18-26%, granules are formed, which are dried to a moisture content of not more than 7% and fired at a temperature of 1050-1150 ° C.
