HIGH-STRENGTH CONCRETE MIX WITH LOW CEMENT CONSUMPTION Russian patent published in 2022 - IPC C04B28/04 C04B14/06 C04B18/14 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to modified concrete mixtures. The concrete mixture includes cement with a specific surface area of ​​2800-4500 cm²/g, quartz sand, coarse aggregate, additionally contains ground blast-furnace slag with a specific surface area of ​​2500-4500 cm²/g with a CaO content of at least 30%, microsilica with a specific surface area of ​​140,000 - 300,000 cm²/g, plasticizer based on carboxylates, with the following ratio of components indicated in wt.%: cement - 2.1-4.2; sand - 29.4-37.8; ground slag - 14.7-16.8; microsilica - 1.3-2.5; plasticizer based on carboxylates - 0.34-0.63; water - 6.7-7.6; coarse aggregate - crushed stone - the rest.

EFFECT: increasing compressive strength, reducing porosity.
