Abstract
Изобретение относитс к области производства строительных материалов и может быть использовано дл изготовлени легкого заполнител преимущественно из камневидного сырь - ту- фоаргиллита. Дл снижени насыпной плотности заполнител и расширени температурного интервала вспучивани обжигаемые зерна дробленого сырь опудривают смесью из 75-90 мас,% доломита и 10-25 мас,% андезита. 1 табл. N3 СО со со CDThe invention relates to the production of building materials and can be used for the manufacture of a lightweight aggregate, mainly from tuffaceous rock-like raw material. To reduce the bulk density of the aggregate and extend the temperature range of expansion, the burning grains of crushed raw material are powdered with a mixture of 75-90 wt.% Dolomite and 10-25 wt.% Andesite. 1 tab.

Изобретение относитс к производству строительных материалов и может быть использовано дл изготовлени легкого заполнител преимущественно из камневидного сырь , в частности туфоаргиллита.The invention relates to the production of building materials and can be used for the manufacture of lightweight aggregates, mainly from stone-like raw materials, in particular tuffargillite.
Цель изобретени - снижение насыпной плотности заполнител и расширение температурного интервала вспучивани .The purpose of the invention is to reduce the bulk density of the aggregate and to extend the temperature range of expansion.
Способ изготовлени легкого заполнител преимущественно из туфоаргиллита включает дробление, сьфь , фракA method of manufacturing a lightweight filler, predominantly of tuffargillite, includes crushing, cf, dressing
Соотношение компонентов в опудривающей смеси, мае.%:The ratio of components in the powder mixture, wt.%:
доломитdolomite
андезитandesite
Температура обжига опудренных зерен изThe roasting temperature of powdered grains from
75 85 90 - Смесь известн - 25 15 10 ка и золы75 85 90 - A mixture of limestone - 25 15 10 ka and ashes
Предлагаемый способ обеспечивает при обжиге дробленого туфоаргиллита снижение насыпной плотности до уровн 290-310 кг/м против 350 кг/м и расширение температурного интервала вспучивани до 100-110°С против 90 С при использовании известного способа.When the crushed tuffargillite is roasted, the proposed method reduces the bulk density to 290–310 kg / m versus 350 kg / m and extends the expansion temperature range to 100–110 ° C versus 90 C using the known method.
