Description

Изобретение относится к промышленности строительных материалов.The invention relates to the construction materials industry.

Известна сырьевая смесь для получения глиноземистого цемента, включающая бокситы и известь [1].Known raw mix for producing alumina cement, including bauxite and lime [1].

Известна сырьевая смесь для получения глиноземистого цемента, содержащая, мас.%: шлак алюминотермического производства 70-95; шлак доменной бокситной плавки 5-30 [2].Known raw material mixture for producing alumina cement, containing, wt.%: Slag aluminothermic production 70-95; blast furnace bauxite smelting slag 5-30 [2].

Цель изобретения состоит в повышении прочности цемента.The purpose of the invention is to increase the strength of cement.

Цель достигается тем, что в состав сырьевой смеси для получения цемента, содержащей шлак алюминотермического производства и шлак доменной бокситной плавки, дополнительно вводят алюмощелочной шлам, при следующем соотношении компонентов, мас.%: шлак алюминотермического производства 74-76; шлак доменной бокситной плавки 18-22; алюмощелочной шлам 4-6.The goal is achieved by the fact that in the composition of the raw material mixture for cement, containing slag aluminothermic production and slag blast furnace bauxite, additionally enter alumina alkaline slurry, in the following ratio, wt.%: Slag aluminothermic production 74-76; bauxite blast furnace slag 18-22; aluminum-alkaline sludge 4-6.

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

Шлак алюмотермического производства, шлак доменной бокситной плавки измельчают, добавляют алюмощелочной шлам, перемешивают и подают в печь, где обжигают при 1300-1400°С. Клинкер охлаждают струей воздуха и измельчают до порошкообразного состояния.Slag of aluminothermic production, slag of blast furnace bauxite smelting is crushed, aluminum-alkaline slurry is added, mixed and fed to the furnace, where it is calcined at 1300-1400 ° С. The clinker is cooled by a stream of air and crushed to a powder state.

Шлак алюминотермического производства содержит до 80 мас.% диалюмината кальция.Slag aluminothermic production contains up to 80 wt.% Calcium dialuminate.

Шлак доменной бокситной плавки содержит до 90 мас.% моноалюмината кальция и небольшое количество 12 СаО·7 Al2O3,Bauxite smelting blast furnace slag contains up to 90 wt.% Calcium monoaluminate and a small amount of 12 CaO · 7 Al 2 O 3 ,

Алюмощелочной шлам является отходом щелочного травления алюминия и содержит приблизительно в равных долях гидроксид алюминия и щелочь.Alumina alkali sludge is a waste product of alkaline etching of aluminum and contains approximately equal proportions of aluminum hydroxide and alkali.
