Description

Разрушение каолинита при более -низких температурах и более быстрыми темпами позвол ет ожидать от продуктов этого разрушени  более высокой активности, как следстви  -их дисперсности, дефектов структуры решетки и т. п.The destruction of kaolinite at lower temperatures and at a faster pace allows us to expect from the products of this destruction a higher activity, as a result of their dispersivity, lattice structure defects, etc.

Дл  проверки указанных соображений в отношении активизации свойств обоженного каолинита, как искусственной гидравлической добавки , авторами были параллельно обожжены при температуре 600° образцы каолина с добавкой и безTo verify these considerations with regard to the activation of the properties of calcined kaolinite, as an artificial hydraulic additive, the authors simultaneously burned kaolin samples at 600 ° C with and without additive

добавки хлористого магни . Количество добавленного хлористого магни  составл ло 1,5 % в пересчете на MgO.magnesium chloride supplements. The amount of added magnesium chloride was 1.5% in terms of MgO.

Полученные образцы подвергались размолу до прохождени  через сито 900 otelcM и смешивались с гашеной известью в соотношении I : 1.The obtained samples were ground before passing through a 900 otelcM sieve and mixed with slaked lime in the ratio of I: 1.

Изготовл лс  жесткий раствор с песком в отношении 1 : 3, который подвергалс  формовке и испытани м по Кюлю. Примен лось как водное , так и воздушное хранение.A hard solution was made with sand in the ratio 1: 3, which was molded and tested according to Kühl. Both water and air storage was used.

Полученные результаты позвол ют сделать следующие выводы:The results obtained lead to the following conclusions:

а) добавка магнезиальных соединений активизирует каолин как гидравлическую добавку, значительноувеличива  прочность образцов на сжатие цо сравнению с образцами, изготовленными из в жущего с добавкой чистого каолина;a) the addition of magnesia compounds activates kaolin as a hydraulic additive, significantly increasing the compressive strength of the samples compared to samples made from a binder containing pure kaolin;

б) обжиг каолина с магнезиальной добавкой увеличивает воздухостойкость цемента.b) roasting kaolin with magnesia additive increases the air resistance of the cement.

Предмет изобретени Subject invention

Способ получений гидравлических добавок путем обжига каолинитовых материалов, отличающийс   тем, что, с целью повышени  активности получаемых гидравлических добавсщ, обжиг ведут в присутствии соединени  или соединений магни .A method of obtaining hydraulic additives by calcining kaolin materials, characterized in that, in order to increase the activity of the resulting hydraulic additives, the calcination is carried out in the presence of a compound or magnesium compounds.
