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.

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%.
