HIGH-STRENGTH POWDER-ACTIVATED CONCRETE Russian patent published in 2020 - IPC C04B28/02 

FIELD: construction.

SUBSTANCE: invention relates to construction materials and can be used in production of structures and articles from concrete on cement binder for buildings and structures of civil, industrial and special purposes. High-strength powder-activated concrete contains composite portland based on portland cement clinker in amount of 70 %, finely ground granulated slag 26 %, dihydrate gypsum 3 % and sodium fluoride 1 %, filler - fine powder of quartz, limestone and so forth, with specific surface area of 600 m²/kg, filler - quartz sand of fraction of 0.63–5.0 mm, Melflux 2651 F hyperplasticiser and tempering water. As tempering water contains activated water, which has passed electrochemical and electromagnetic activation with introduction of oxide-hydroxide compounds of aluminium and iron in amount of 2…10 g/m³.

EFFECT: technical result consists in creation of high-strength powder-activated concrete with low consumption of cement clinker and high biological stability due to rationally selected composition, which includes composite binder and activated brewing water.
