FIELD: building materials.
SUBSTANCE: invention relates to the building materials industry. The composition for the restoration of reinforced concrete structures contains components in the following ratio, wt. %: cement binder 22.72-25.15; fractionated quartz sand after 2-fold treatment with NMCP 63.33-67.74; chlorine-free reactive additive 0.32-0.45; production waste of a structured ferromagnetic microwire with a diameter of 5-35 microns and a length of 10-15 mm 0.05-0.25; an aqueous suspension of nanocrystalline cellulose containing 0.7-4.8 wt.% NCC, 3.81-8.57%; mixing water - the rest.
EFFECT: increasing the rate of cement hardening, water resistance, tensile and bending strength of the compositions.
