Description
Из отовление расшир ющегос цемент производитс смещением портландцемента , высокопрочного гипса н гидроалюмината кальци , который в серого порошка получаетс при обработке двух весовых чаете глиноземистого цемента одной частью известкового теста в водной суспензии вначале при комнатной температуре, а затем при 120-150 до полного удалени влаги . Необходимый дл приготовлени гидроалюмииата кальци глиноземистый цемент производитс в ограниченном количестве и признаетс дефицитным материалом.The expansion cement is produced by displacing Portland cement, high-strength gypsum n calcium hydroaluminate, which in gray powder is obtained by treating two weight alumina cement with one part of the lime paste in the aqueous suspension first at room temperature and then at 120-150 until moisture is removed. The alumina cement required for the preparation of calcium hydroalumium is produced in limited quantities and is recognized as a deficient material.
Описываемый способ изготовлени расншр юнгегос цемента не требует применени глиноземистого це мента .The described method for the production of cement cement does not require the use of alumina cement.
Особенность предлагаемого способа состоит в тодг, что глиноземистый цеме1гг замен етс природным алу}гнтол (квасцовым камнем), залежи которого встречаютс во многих местах и содержат от 50 до 57% алун1гга.The peculiarity of the proposed method is that the aluminous cement is replaced by natural alu} gtol (alum stone), deposits of which are found in many places and contain from 50 to 57% of alumini.
Процесс приготовлени гидроалюмината кальци на алуните сохран етс такнм же, как и дл глиноземистого цемента. В котел загружают одну весовую часть измельченного в порошок или молотого алунита, добавл ют одну весовую часть извести пушенки и воды; в течение нескольких часов при комнатной температуре массу вначале перемешивают, а затем нагревают до 120-130° и довод т, в течение 4-5 час., до полного обезвоживани и образовани из нее сухого порошка .The process for preparing calcium hydroaluminate on alunite is the same as for alumina cement. One weight part of the powdered or ground alunite is loaded into the boiler, one weight part of the lime powder and water is added; for several hours at room temperature, the mass is first stirred, and then heated to 120-130 ° and adjusted, for 4-5 hours, until complete dehydration and the formation of a dry powder from it.
В св зи с этим отпадает необходимость в расходовании глиноземистого цемента, который замен етс недефицитным и деи.гевым естественным минералом.In this connection, there is no need to expend alumina cement, which is replaced by a non-deficient and deiyevy natural mineral.
Дополинтельна экономи достигаетс за счет снижени расхода гипса. При обычном способе в расшир юн ийс цемент ввод т 20% гипса. В описываемом способе из алунита, нар ду с алюминатом, образуетс гипс. Количество его составл ет по расчету около 20% от расшир ющей добавки. Поскольку в расшир ющийс цемент вводитс 10% добавки, то этим вноситс одновременно 3% гипса. Следовательно, общий расход гипса может быть снижен с 20 до 17%.Additional savings are achieved by reducing the consumption of gypsum. In a conventional process, 20% of gypsum is injected into the cement. In this process, gypsum is formed from alunite, along with aluminate. Its amount is based on the calculation of about 20% of the expansion additive. Since 10% of the additive is added to the expanding cement, 3% of the gypsum is applied simultaneously. Consequently, the total consumption of gypsum can be reduced from 20 to 17%.
