Description

Изобретение относится к производству бетонов, которые могут быть использованы при строительстве тепловых агрегатов.The invention relates to the production of concrete, which can be used in the construction of thermal units.

Известна огнеупорная бетонная смесь, содержащая следующие компоненты, мас. %: связующее 8,0-17,0; каолин 19,0-28,0; стальное волокно 1,0-3,0; шамот - остальное [1].Known refractory concrete mixture containing the following components, wt. %: binder 8.0-17.0; kaolin 19.0-28.0; steel fiber 1.0-3.0; chamotte - the rest [1].

Задача изобретения состоит в повышении термостойкости бетона, полученного из смеси.The objective of the invention is to increase the heat resistance of concrete obtained from the mixture.

Технический результат достигается тем, что огнеупорная бетонная смесь, включающая связующее, каолин, стальное волокно, шамот, в качестве связующего содержит глиноземистый цемент и дополнительно - доменный шлак, при следующем соотношении компонентов, мас. %: глиноземистый цемент 27,0-28,0; каолин 0,5-1,0; стальное волокно длиной 5-10 мм 1,0-3,0; измельченный и просеянный через сетку №063 доменный шлак 8,0-12,0; шамот - остальное, при водоцементном отношении 0,5-0,6.The technical result is achieved in that the refractory concrete mixture, including a binder, kaolin, steel fiber, chamotte, contains alumina cement and optionally blast furnace slag as a binder, in the following ratio of components, wt. %: alumina cement 27.0-28.0; kaolin 0.5-1.0; steel fiber 5-10 mm long 1.0-3.0; crushed and sifted through mesh No. 063 blast furnace slag 8.0-12.0; chamotte - the rest, with a water-cement ratio of 0.5-0.6.

В таблице приведены составы огнеупорной бетонной смеси.The table shows the composition of the refractory concrete mixture.

Компоненты дозируют в требуемых количествах и смешивают. Смесь укладывают в смазанные маслом металлические формы, уплотняют и оставляют до затвердевания. Готовые изделия (блоки) извлекают из форм и при необходимости подвергают механической обработке (распиловке на плиты).The components are metered in the required amounts and mixed. The mixture is placed in greased metal molds, compacted and left to harden. Finished products (blocks) are removed from the molds and, if necessary, subjected to mechanical processing (sawing into plates).
