COMPOSITION FOR THE RESTORATION OF REINFORCED CONCRETE STRUCTURES OF COMMUNICATION COLLECTORS Russian patent published in 2021 - IPC C04B28/02 C04B22/00 C04B18/04 

FIELD: building materials.

SUBSTANCE: invention relates to the industry of building materials. The composition for the restoration of reinforced concrete structures contains a cement binder, fractionated quartz sand, a chlorine-free chemically active additive, polymer or mineral fiber and mixing water, while for its manufacture, fractionated quartz sand is used that has undergone 2-fold treatment with low-temperature nonequilibrium plasma (LTNP), mixing water, consisting of a mixture of ordinary water and water treated with low-temperature nonequilibrium plasma at a ratio of 1: 1, and as a mineral fiber contains waste from the production of a structured ferromagnetic microwire with a diameter of 5-35 μm and a length of 10-15 mm with the following ratio of components, wt. %: Portland cement 22.72-25.15, fractionated quartz sand after 2-fold treatment with LTNP 63.33-67.74, chlorine-free chemically active additive 0.38-0.65, production waste of structured ferromagnetic microwire with a diameter of 5-35 microns and a length of 10-15 mm 0.05-0.25, mixing water, consisting of a mixture of ordinary mixing water and water treated with LTNP in a plasma-chemical reactor at a ratio of 1: 1 the rest.

EFFECT: reducing water-cement ratio, accelerating the strength gain of the composition in the initial period of hardening, increasing bending and tensile strength of cement-based repair building compounds.
