Description

Способ получени  глиноземистого цемента дл  возведени  бетонных и железобетонных сооружений известен. Но получаемый цемент обладает существенным недостатком, заключающимс  в высокой экзотермии процессов схватывани  и твердени , что приводит к по влению больших внутренних напр жений, которые в значительной степени снижают механическую прочность всей конструкции. Характерным дл  бетонов и растворов на этом цементе  вл етс  быстрое высыхание поверхностей и крошение ребер и углов при твердении на воздухе.A method for producing alumina cement for building concrete and reinforced concrete structures is known. But the resulting cement has a significant drawback consisting in the high exotherm of the setting and hardening processes, which leads to the appearance of large internal stresses, which greatly reduce the mechanical strength of the whole structure. Characteristic of concretes and mortars on this cement is the quick drying of the surfaces and the crushing of the edges and corners when cured in air.

Предложенный способ получени  цемента заключаетс  в добавке к цементу природного глауконита. Глауконит добавл етс  к цементу в пределах от 5 до 10% от веса цемента. При способе введени  в доменный глиноземистый цемент глауконита механическа  прочность его при хранении на воздухе остаетс  почти такой же, как прочность образцов, хранившихс  в воде. Прочность же доменного глиноземистого цемепта без добавлени  глауконита при хранении его на воздухе падает в 2-3 раза по сравнению с таким же цементом, сохран вшимс  в воде.The proposed method for producing cement is in addition to cement natural glauconite. Glauconite is added to cement ranging from 5 to 10% by weight of cement. With the method of introducing glauconite into blast furnace alumina cement, its mechanical strength during storage in air remains almost the same as that of samples stored in water. The strength of the blast furnace alumina cement without the addition of glauconite during storage in air decreases by a factor of 2-3 compared with the same cement stored in water.

Образцы доменного глиноземистого цемента с введенным глаукони том, твердевшие на воздухе, не приводили к крошению ребер и углов, как это наблюдалось в образцах доменного глиноземистого цемента без добавки глауконита, и значительно повышали механическую прочность конструкции.Samples of blast-furnace aluminous cement with introduced glauconit, hardened in air, did not lead to crumbling of edges and corners, as was observed in samples of blast-furnace aluminous cement without the addition of glauconite, and significantly increased the mechanical strength of the structure.

Предмет изобретени Subject invention

Способ получени  цемента, например, глиноземистого, отличающийс  тем, что, с целью понижени  экзотермического эффекта процессов схватывани  и твердени , в готовый глиноземистый цемент ввод т в качестве добавки глауконит.A method of producing cement, for example, aluminous, characterized in that, in order to reduce the exothermic effect of the setting and hardening processes, glauconite is added to the finished alumina cement.
