Description
(54) МИНЕРАЛЬНАЯ ДОБАВКА К ЦЕМЕНТУ(54) MINERAL ADDITION TO CEMENT
1one
Изобретение относитс к области строительных материалов и может быть использовано в цементной промышленности .The invention relates to the field of building materials and can be used in the cement industry.
Известно введение в цемент в качестве добавки перлита в количестве 15-85% 1 . .Known introduction to cement as an additive perlite in the amount of 15-85% 1. .
Недостатком известного состава в жущего с добавкой перлита вл етс его низка прочность.The disadvantage of the known perlite-containing compound composition is its low strength.
Наиболее близкой к изобретению по технической сущности и достигаемому эффекту вл етс добавка к портландцементу до 10% золы ТЭЦ |2}.Closest to the invention in its technical essence and the effect achieved is an addition to Portland cement of up to 10% of ash CHP | 2}.
Недостатком известного в жущего на основе портландцемента с добавкой золы вл ютс низка прочность и юрозостойкость .A disadvantage of the known portland cement based additive with low ash content is low strength and resistance to frost.
Цель изобретени - повышение прочности и морозостойкости цемента.The purpose of the invention is to increase the strength and frost resistance of cement.

Клинкер ДобавкаClinker Additive
Поставленна цель достигаетс тем, что минеральна добавка к цементу, включающа золу, дополнительно содержит перлит-сырец при следукадем соотношении комЛонентбв, вес.%: Зола 95 - 96 Перлит-сырец 4-5The goal is achieved by the fact that the mineral additive to cement, including ash, additionally contains raw pearlite at the following ratio of comonentbw, wt.%: Ash 95 - 96 Rawlit raw 4-5
Перлит-сырец размалываетс до „ удельной поверхности 4000-5000 см /г и добавл етс к золе.Raw perlite is ground to a specific surface of 4000-5000 cm / g and added to the ashes.

В таблице приведены физико-механические свойства цементов.The table shows the physico-mechanical properties of cements.
Исследование провод т на основе клинкера Ангарского цемзавода марки 400.The study was carried out on the basis of clinker of Angarsk cement plant brand 400.
Состав добавки:The composition of the additive:
Из таблицы видно, что цементы с . введением золы имеют прочность 36 МПа.20 При добавке 4,5% молотого перлитсьфца прочность смешанного в жущего значительно увеличиваетс и составл ет 43 МПа, введение 5% молотого net ;лит-сьв ца повышает прочность до 25 46 МПа. В св зи с повьииением прочности возможна экономи цемента до 10%, что дает экономический эффект 0,88руб, на 1 м бетона. Морозостойкость увеличиваетс с 200 до 250 циклов.The table shows that the cements with. The introduction of ash has a strength of 36 MPa.20 With the addition of 4.5% ground perlitsfetz, the strength of the mixed binder increases significantly and is 43 MPa, the introduction of 5% of ground net; literature increases the strength to 25 46 MPa. In connection with the increase in strength, it is possible to save cement up to 10%, which gives an economic effect of 0.88 rubles per 1 m of concrete. Frost resistance is increased from 200 to 250 cycles.
