Аннотация: The article discusses the possibility of using alumina nanofibers to reinforcement cement mortar. Nanofiber is a twisted conglomerate, and its ultrasonic treatment in the water allows obtaining a stable dispersion. The research has been carried out on the effect of nanofibers on the viscosity of cement paste, as well as on the reinПоказать полностьюforcement of cement mortar. At concentrations less than 0,2%, there is no significant effect of nanofibers on the viscosity of the system. The studies were carried out on standard Portland cement at a water-cement ratio of 0.27. Reinforcement of cement mortar with aluminum oxide, with a concentration of 0 to 0.1%, does not give a significant change in the microstructure of the material. It was shown in the work that the use of nanofibers makes it possible to increase the strength of the system by 20% in compression and by 45% in bending.
