Description
(54) СПОСОБ ПРОИЗВОДСТВА ЛЕГКОГО ЖАРОСТОЙКОГО БЕТОНА(54) METHOD OF MANUFACTURE OF LIGHT HEAT-RESISTANT CONCRETE
1one
Изобретение относитс к технологии строительных материалов, в частности к способу производства легкого жаростойкого бетона,The invention relates to the technology of building materials, in particular to a method for the production of light heat-resistant concrete,
Известен способ производства жаростойкого бетона, заключающийс в приготовлении бетонной смеси с последующим прессованием ее и термообработкой.A known method for the production of refractory concrete involves the preparation of a concrete mix, followed by pressing and heat treatment.
Однако свежесформованные издели , полученные по известному способу, недостаточно прочны; кроме того, технологи про изводства бетона очень сложна.However, the newly formed products obtained by a known method, not strong enough; In addition, the technology of concrete production is very difficult.
Цель изобретени - увеличение прочности свежесформованных изделий и упрощение технологии.The purpose of the invention is to increase the strength of the newly formed products and simplify the technology.
I: Предлагаемый способ позвол ет исключить промежуточную операцию термообработки при температуре 1ОО-15ОоС, сократить расход в жущего до 1О% и снизить стоимость бетона до 20 руб на 1 м .I: The proposed method makes it possible to eliminate the intermediate heat treatment operation at a temperature of 1OO-15 ° C, reduce the consumption of live concrete to 1 O% and reduce the cost of concrete to 20 rubles per 1 m.
Пример получени легкого жаростойкого бетона: полусухую смесь готов т из ортофосфорной кислоты, хромалюфосфатной св зи, технического глинозема и керамзита перемешиванием в мешалке принудительного действи и формуют на прессе при . удельном давлении 80 кг/см. Свежесформованные издели термообрабатывают при температуре 800°С, после чего издели готовы к употреблению.An example of obtaining lightweight refractory concrete: semi-dry mixture is prepared from orthophosphoric acid, chromium-phosphate bond, technical alumina and claydite by mixing in a forced-action mixer and molded on a press at. specific pressure 80 kg / cm. Freshly formed products are thermoablative at a temperature of 800 ° C, after which the products are ready for use.
