Description
Изобретение представл ет способ повышени прочности доломитового в жущего путем добавлени к доломиту , обожженному до температуры 600-650°, в процессе помола 0,5-5% гипса.The invention provides a method for increasing the strength of a dolomite slag by adding to dolomite calcined to a temperature of 600-650 °, in the process of grinding 0.5-5% gypsum.
Исследовани ми установлено, что весьма положительные результаты могут быть получены в случае добавлени к полуобожженному доломиту при его водном затворении небольшого количества сернокислого кальпи в любой его модификации (двугидрат, полугидрат, ангидрит).Research has shown that very positive results can be obtained if dolomite is added to semi-calcined dolomite when it is water-mixed, with a small amount of calcium sulphate in any modification (dihydrate, hemihydrate, anhydrite).
Установлено также, что вли ние добавки сернокислого кальци про вл етс особенно эффективно при малом содержании окиси кальци или гидрата окиси кальци , когда вообще наблюдаетс повышенна прочность в жущего.It has also been found that the effect of the calcium sulfate additive is particularly effective with a low content of calcium oxide or calcium oxide hydrate, when an increased strength of the binder is generally observed.
Пониженное содержание активной окиси кальци и одновременное повышение прочности может быть достигнуто р дом способов:A reduced content of active calcium oxide and a simultaneous increase in strength can be achieved in a number of ways:
1) добавлением в процессе обжига доломита веществ, вступающих в химическое взаимодействие с активной окисью кальци , например, глины;1) adding, during the burning process of dolomite, substances that enter into chemical interaction with active calcium oxide, for example, clay;
2)добавлением при обжиге доломита в интервале температур 600-650° в процессе помола веществ , св зывающих активную окись кальци , как например, молотой цем нки, диатомовых горных пород, золы от пылевидного сжигани угл и т. п. Положительный эффект усугубл етс при этом гидротермальной обработкой изде.т1|ИЙ из доломита;2) adding dolomite in the temperature range 600–650 ° during calcining in the process of grinding substances that bind active calcium oxide, such as ground cement, diatomaceous rocks, ash from pulverized coal, etc. The positive effect is exacerbated by this hydrothermal treatment of articles t1 | II from dolomite;
3)обжигом доломита в течение длительного срока при пониженной температуре (550-650°);3) roasting dolomite for a long time at a low temperature (550-650 °);
4)св зыванием свободной окиси кальци путем длительного выдерживани размолотого продукта на воздухе или в среде, обогащенной углекислотой газа (возможно с продуванием его через слой в жущего ) .4) by binding the free calcium oxide by long-term keeping the ground product in air or in an environment enriched with carbon dioxide gas (possibly with blowing it through a layer into a binder).
