NANOMODIFIER OF CONSTRUCTION MATERIALS Russian patent published in 2017 - IPC C04B28/02 C04B14/38 C04B24/24 B82B1/00 C04B111/20 

FIELD: nanotechnology.

SUBSTANCE: nanomodifier on a cement binder is described, comprising a mixture containing carbon nanomaterial (CNM), a filler and a plasticiser, wherein the CNM is introduced as an aqueous suspension that has been processed in an ultrasonic unit at an operating frequency of 16-25 kHz and a power of at least 100-500 W and containing potassium polititanate (PPT), CNM "Taunit" and polyvinyl pyrrolidone (PVP) with the following component ratio: potassium polititanate (PPT)-7-9×10^-4%, carbon nanomaterial (CNM "Taunit") - 5-7% and polyvinyl pyrrolidone (PVP)- 1-1,6×10^-3% weight of the cement binder.

EFFECT: increasing the strength of concrete for compression and strength set at an earlier time, while simultaneous increasing the density, water resistance and crack resistance of construction composite.
