Description
Изыскива способы устранени потери прочности и ползучести изделий из гипсовых в жущих при их увлажнении, авторы установили, что добавка к гипсу, обожженному при 600-750 ТЭЦ-цемента или смеси его с гранулированными доменными щлаками дает возможность получить цемент , который отличаетс гидравличностью , отсутствием ползучести и посто нством объема.Looking for ways to eliminate the loss of strength and creep of gypsum products stinging when wetted, the authors found that an additive to gypsum calcined at 600-750 CHP-cement or its mixture with granulated blast furnace slabs makes it possible to obtain cement that is hydraulically non-creeping and constant volume.
ТЭЦ-цемент получаетс при сжигании в топках теплоэлектроцентралей пылевидного топлива с добавкой 15-35% молотого известн ка или мела. ТЭЦ-цемент состоит из двухкальциевого силиката, алюминатов и ферритов кальци , свободной извести и золы. Этот цемент не обладает равномерностью изменени объема, что тормозит его распространение .CHP-cement is obtained by burning pulverized fuel with the addition of 15-35% of ground limestone or chalk in the heating plants of the combined heat and power plants. CHP-cement consists of dicalcium silicate, aluminates and calcium ferrite, free lime and ash. This cement does not have a uniform change in volume, which inhibits its distribution.
Положительное вли ние ТЭЦ-цемента на ангидрид объ сн етс авторами тем, что свободна известь ТЭЦ-цемента вл етс катализатором при гидратации ангидрита; образующийс же при гидратации ТЭЦцемента гидросиликат кальци обволакивает частицы гипсового в жущего , а тонкодисперсный кремнезел и другие колшоненты золы заполн ют поры в жущего и тем самым придают гипсовому в жущему гидравличность и повышенную прочность.The positive effect of CHP-cement on the anhydride is attributed to the fact that the free lime of CHP-cement is a catalyst for the hydration of anhydrite; Calcium hydrosilicate formed during the hydration of CHP cement envelops particles of gypsum in the binder, while fine silica gel and other ash particles fill the pores of the binder and thereby give hydraulics and increased strength to the gypsum in the binder.
В отличие от других катализаторов , примен емых при производстве ангидритового цемента, ТЭЦ-цемент или смесь его с гранулированными доменными шлаками, будучи добавлены в количестве от 5 до , дает возможность получить высокопрочный ангидритовый цемент с прочностью на сжатие через 3 дн 200- 300 кг/см при хранении во влажной среде или 350-400 при высушивании до посто нного веса при 60-70° после трехдневного хранени во влажной среде. Цемент такого качества может найти широкое применение при восстановительном и новом строительстве, как быстротвердеющий цел1ент, в качестве раствора дл каменной кладки и штукатурки, а также дл изготовлени различного р да строй деталей.Unlike other catalysts used in the production of anhydrite cement, CHP-cement or a mixture of it with granulated blast-furnace slags, being added in the amount of from 5 to, makes it possible to obtain high-strength anhydrite cement with compressive strength after 3 days 200-300 kg / cm when stored in a humid environment or 350-400 when dried to constant weight at 60-70 ° after three days of storage in a moist environment. Cement of this quality can be widely used in renovation and new construction, as a fast-hardening cement, as a mortar for masonry and plaster, as well as for the manufacture of various types of components.
413 № 69294 Предмет изобретени Способ получени ангидритового цемента, отличающийс тем, что, в цел х повышени прочности и гидравличности гипсового в жущего, искусственному или природному ангидриту добавл ют ТЭЦ-цемент или смесь последнего с гранулированным шлаком при помоле или путем смешени измельченных компонентов .413 No. 69294 Subject of the Invention A method for producing anhydrite cement, characterized in that, in order to increase the strength and hydraulics of gypsum cement, artificial heat or natural anhydrite is added to the CHP-cement or mixture of the latter with granulated slag during grinding or by mixing ground components.
