Description

Изобретение относится к составам сырьевых смесей для производства портландцементного клинкера.The invention relates to compositions of raw mixes for the production of Portland cement clinker.

Известен портландцементный клинкер, получаемый из сырьевых смесей на основе известкового и глинистого компонентов /1/.Known Portland cement clinker obtained from raw mixtures based on lime and clay components / 1 /.

Известна сырьевая смесь следующего состава, мас.%: глинистый компонент 13-21; железосодержащий компонент 1-2,5; отсев продукта сжигания твердых бытовых отходов на основе SiO2 1-8; известковый компонент - остальное /2/.Known raw material mixture of the following composition, wt.%: Clay component 13-21; iron component 1-2.5; screening of the product of burning solid waste based on SiO 2 1-8; calcareous component - the rest / 2 /.

Цель изобретения - повышение прочности.The purpose of the invention is to increase strength.

Цель достигается тем, что в состав сырьевой смеси, содержащей глинистый компонент, железосодержащий компонент, известковый компонент, дополнительно вводят сернокислый глинозем, а в качестве железосодержащего компонента - доменный шлак, при следующем соотношении, мас.%: глинистый компонент 15-20; доменный шлак 13-20; сернокислый глинозем 0,3-0,5; известковый компонент - остальное.The goal is achieved in that in the composition of the raw material mixture containing a clay component, an iron-containing component, a calcareous component, alumina sulfate is additionally introduced, and blast furnace slag is used as an iron-containing component, in the following ratio, wt.%: Clay component 15-20; blast furnace slag 13-20; alumina sulfate 0.3-0.5; the calcareous component is the rest.

В таблице приведены составы сырьевой смеси.The table shows the composition of the raw mix.
