METHOD TO REINFORCE AND REPAIR REINFORCED CONCRETE STACK Russian patent published in 2012 - IPC E04H12/28 

Abstract RU 2443838 C2

FIELD: construction.

SUBSTANCE: method to reinforce and repair reinforced concrete stacks with the help of a strengthening reinforced concrete shell, installed onto a damaged internal or external surface of the stack shaft and including previous cleaning of the surface from damaged concrete and corrosion traces, in which the damaged and previously cleaned surface of the stack shaft is in turns and in separate sections coated with synthetic resin having strengthening heat-resistant fibres, and composition of the shell concrete also includes strengthening heat-resistant fibres, at the same time concrete compaction until resin hardening is carried out by vibration pressing, and the external surface of the shell is formed by the left formwork, fixed by synthetic resin with heat-resistant fibres and bolts, which are previously fixed in the stack shaft concrete.

EFFECT: reduced material intensity and labour intensiveness in performance of works.
