CHARGE FOR THE MANUFACTURE OF CELLULAR HEAT-RESISTANT CONCRETE Russian patent published in 2022 - IPC C04B38/10 C04B28/04 C04B28/06 C04B111/20 

FIELD: construction materials.

SUBSTANCE: invention relates to the field of construction materials, in particular to heat-resistant concrete intended for use in conditions of elevated temperatures. The charge for the manufacture of cellular heat-resistant concrete on a cement binder contains, wt. %: Portland cement CEM II/A-W 42.5N 39.07-42.64, sand with a grain size of no more than 0.63 mm 5.43-5.77, chamotte powder with a particle size of no more than 0.63 mm 4.93-5.23, protein-based foaming agent 0.04-0.06, alumina cement 2.09-2.21, granulated blast furnace slag with a particle size of no more than 0.63 mm 14.53-15.43, basalt powder with a particle size of no more than 0.63 mm 10.74-11.41, basalt fiber with a fiber size of 6-12 mm 0.83-0.89, water 18.77-19.93.

EFFECT: increase in compressive strength and an increase in the number of air heat transfers.
