Изобретение относитс к промышленности строительных материалов и может быть использовано на заводах, выпускающих жаростойкий бетон и элементы конструкций тепловых агрегатов из жаростойкого бетона .The invention relates to the building materials industry and can be used in factories producing heat-resistant concrete and structural elements of heat units from heat-resistant concrete.
Известна бетонна смесь дл изготовлени жаростойких изделий, включающа жидкое стекло, тонкомолотый магнезит , добавку, заполнитель-шлак от выплавки хрома l.The known concrete mixture for the manufacture of heat-resistant products, including liquid glass, finely ground magnesite, an additive, aggregate-slag from the smelting of chromium l.
Однако эта смесь имеет недостаточно высокую остаточную прочность.However, this mixture has an insufficiently high residual strength.
Известна бетонна смесь дл изготовлени жаростойких изделий, включающа жидкое стекло, активизатор твердени , магнезит тонкомолотый, заполнитель и тонкомолотую добавку 2 Така смесь вл етс наиболее близкой по технической сущности и достигаемому эффекту к изобретению.The known concrete mixture for the manufacture of heat-resistant products, including water glass, a hardening activator, finely ground magnesite, aggregate, and finely ground additive 2 This mixture is the closest in technical essence and effect to the invention.
Недостатком ее вл етс низка остаточна прочность, огнеупорность и температура применени .Its disadvantage is low residual strength, refractoriness and temperature of use.
Цель изобретени - повышение остаточной прочности, огнеупорности и температуры применени .The purpose of the invention is to increase the residual strength, refractoriness and temperature of use.
Это достигаетс тем, что бетонна смесь содержит жидкое стекло, активизатор твердени , магнезит тонкомолотый , а в качестве заполнител шлак углеродистого предельного феррохрома фракции 0,14-10 мм и в качестве добавки - шлак углеродистого передельного феррохрома удельной поверхности .2000-5000 см /г при следующем соотношении компонентов, вес,%:This is achieved by the fact that the concrete mixture contains liquid glass, a hardening activator, magnesite is finely ground, and as a filler is carbonaceous limiting ferrochrome of a fraction of 0.14-10 mm and, as an additive, slag of carbon conversion ferrochrome specific surface .2000-5000 cm / g in the following ratio of components, weight,%:

Процесс приготовлени данного беона заключаетс в тщательном перемеивании компонентов смеси, формовании зделий и выдержке в воздушно-сухих слови х в течение 3 сут.The process of preparation of this bona fide consists in carefully mixing the components of the mixture, molding the objects and aging in airy dry words for 3 days.
Сыпучие компоненты смеси перемешивают между собой, после чего в них добавл ют жидкое стекло, массу тщательно перемешивают, укладывают в с приложением вибрировани , после 3-суточной выдержки образцы - кубы см подвергают сушке до пос- . нного веса и испытанию по методике,The loose components of the mixture are mixed together, after which liquid glass is added to them, the mass is thoroughly mixed, placed in with the application of vibrations, and after 3 days of holding the samples — cubes cm are dried until after. weight and test according to the method
