The article discusses the prospects and features of application of the nano-fibers from AlOOH and γ, δ-Al2O3 in fine concrete. Showed the results experimental studies to determine the properties of fine concretes with the addition of nanofibers in an amount of 3,8 and 13% by weight of the binder. Determined the influence on the properties of fine concrete mixtures by different content of nanofibers. Maximal effect from introducing nanofibers into fine concretes affects on elastic modulus, whose value is increased from 18,3 GPa to 40,9 GPa, depending on the dosage of the additive. Found that the introduction of 8% nanofibers by weight of the binder causes a decrease in strength characteristics due to the increased porosity of the composites, and only entering 13% of the fibers increases the strength characteristics on 25%.
