Description

БеТой может найти примеиен-ие ПРИ обмуровке паротенераторов, топок паровых котлов .BETHOY can find an application for lining the steam generators, the furnaces of steam boilers.

.Иэвесте жаростойкий бетол автоклавной обработки на основе лортландцеме та, содержащий даба:ва у и наполииТель, например тонкомолотый шамот, кизельгур, керамзит, шлаК и др. Предварительно обожжеиные добавки такого бетон-а интенсивно и наиболее .полно св зывают окись кальци  лишь :при температурах пор д ка 600-800° С. Поскольку в интервалах температур 500-600° С этот процесс .протекает крайне медленно и иеполео, жа1ростойкий бетон в интервале этих темшератур недастаточио термостоек и подвергаетс  разрушению. Врем  запарки известного бетона составл ет в среднем 7 час.Yest of a heat-resistant betol of an autoclave treatment based on a Lortlandtsem containing duba: vacu and napoliTiel, for example fine ground chamotte, diatomaceous earth, claydite, slag, etc. temperatures range from 600 to 800 ° C. Since this process takes place very slowly in the temperature ranges of 500-600 ° C and sands, hard concrete in the range of these temperatures is not sufficiently heat-resistant and is destroyed. The curing of known concrete averages 7 hours.

Цель изобретени  - повышение качества бетонка, работающего в интервалах температур 500-600°С, и сокрашение времени запарки . Достигаетс  это тем, что в качестве тоНКОМолотой добавки используют необожженную .гранитную пыль в количестве 7-15% при то.нине помола, хара ктеризующейс  остатком сите N 008 не более 30-40%. Гранитна  ПЫЛЬ включает, в основном, алюмосиликат .кали  (KalSiaOs) до 65-70%, свободный ква1рц до 25% и слюду (биотит и мусковит ) 5-10%.The purpose of the invention is to improve the quality of concrete working in the temperature range of 500-600 ° C, and reducing the time of paring. This is achieved by using an unbaked granitic dust in the amount of 7-15% as a to-grinding additive with that grinding, characterized by sieve residue N 008 not more than 30-40%. Granite DUST includes mainly aluminosilicate potassium (KalSiaOs) up to 65-70%, free quarts up to 25% and mica (biotite and muscovite) 5-10%.
