Description

Изобретение относится к составу сырьевой смеси для получения портландцементного клинкера нормированного минералогического состава. Цемент на основе этого клинкера может найти применение в промышленности строительных материалов и строительстве при изготовлении дорожных и аэродромных покрытий, портовых сооружений, а также в нефтегазодобывающей промышленности при тампонировании нефтяных и газовых скважин. The invention relates to the composition of the raw material mixture to obtain Portland cement clinker normalized mineralogical composition. Cement based on this clinker can find application in the building materials industry and construction in the manufacture of road and airfield coatings, port facilities, as well as in the oil and gas industry for plugging oil and gas wells.

Известна сырьевая смесь для получения клинкера, содержащая алюмосиликатный, карбонатный компоненты, а также криолит и хиолит (см. авт. св. СССР N 1451117, кл. С 04 B 7/42, от 15.01.89 г.). Known raw mix for clinker containing aluminosilicate, carbonate components, as well as cryolite and chiolite (see ed. St. USSR N 1451117, class. 04 B 7/42, from 01/15/89,).

Наиболее близким аналогом является сырьевая смесь для получения портландцементного клинкера, содержащая, мас.%:
Карбонатный компонент - 72-79
Железосодержащий компонент - 1-3
Глинистый компонент в виде меллилитовых сланцев - 18-27
(см. авт. св. СССР N 12636365, кл. C 04 B 7/38 от 15.10.86 г.).
The closest analogue is the raw material mixture for obtaining Portland cement clinker, containing, wt.%:
Carbonate component - 72-79
Iron component - 1-3
Clay component in the form of mellitic schists - 18-27
(see ed. St. USSR N 12636365, class C 04 B 7/38 of 10/15/86).

Настоящее изобретение решает задачу получения цемента с высокими специальными свойствами: повышенной сульфатостойкостью, пониженным водоотделением, пониженными деформациями усадки при хороших прочностных показателях. The present invention solves the problem of obtaining cement with high special properties: increased sulfate resistance, reduced water separation, reduced shrinkage deformation with good strength characteristics.

Поставленная задача решается за счет того, что сырьевая смесь для получения портландцементного клинкера, включающая карбонатный, глинистый и железистый компоненты, дополнительно содержит кремнистый сланец с содержанием двуокиси кремния 80 - 95 мас.% при следующем соотношении компонентов, мас.%:
Глинистый компонент - 10 - 25
Железистый компонент - 0,1 - 5
Указанный кремнистый сланец - 1 - 7
Карбонатный компонент - Остальное
Пример осуществления изобретения.
The problem is solved due to the fact that the raw material mixture for producing Portland cement clinker, including carbonate, clay and glandular components, additionally contains siliceous shale with a content of silicon dioxide of 80 - 95 wt.% In the following ratio of components, wt.%:
Clay component - 10 - 25
Glandular component - 0.1 - 5
Specified siliceous slate - 1 - 7
Carbonate component - Else
An example embodiment of the invention.

Сырьевую смесь готовят смешением карбонатного, глинистого, железистого компонента, а также кремнистого сланца. Полученную смесь измельчают в шаровой мельнице и обжигают во вращающейся печи при максимальной температуре около 1450oC. Полученный клинкер с добавкой гипса около 5 масс.% измельчают до удельной поверхности примерно 350 м2/кг.The raw material mixture is prepared by mixing a carbonate, clay, glandular component, as well as siliceous shale. The resulting mixture was ground in a ball mill and fired in a rotary kiln at a maximum temperature of about 1450 ° C. The resulting clinker with gypsum added about 5 wt.% Was ground to a specific surface of about 350 m 2 / kg.

Составы сырьевой смеси и свойства цемента приведены а табл. 1 и 2. The composition of the raw mix and the properties of cement are given in table. 1 and 2.

Как видно из данных таблицы, использование в составе сырьевой смеси кремнистых сланцев позволяет получить цемент высокого качества с улучшенными специальными свойствами. As can be seen from the table, the use of siliceous shale in the raw material mixture allows to obtain high-quality cement with improved special properties.
