the concrete composite durability, other things being equal, must be assessed based of the chemical-mineralogical hydrated new formations composition characteristics, pore structure and character of the contact zones "matrix - filler", "matrix - reinforcing component." Therefore besides obtaining high physical and mechanical characteristics of the material, it is necessary to take into account the issues of formation and management of optimal composite structure to achieve high durability of the material. The paper considers the influence of multi-walled carbon nanotubes and high activity of metakaolin on the processes of modified basalt fiber concrete (BFC) structure formation. The introduction of nanostructured additives in the BFC contributes to the protection of basalt fiber from the alkaline corrosion due to compaction of the composite structure and bind of free Ca (OH)2 by metakaolin into insoluble calcium hydroaluminosilicates, and to increase their adhesion to the surface basalt fiber by directional formation morphology growths and composition that leads to a positive effect on the composite durability.
