FIELD: construction.SUBSTANCE: method to restore and/or reinforce reinforced concrete structures includes cleaning of the surface layer of concrete and further application of a polymer cement primer layer onto the cleaned surface. Further the reinforcing element is fixed on the surface of the restored structure, and the protective layer of the polymer cement mortar is applied manually or in a mechanised manner. The reinforcing element is a net of high-strength fibres fixed on the surface of the restored structure, and this net, prior to its installation into the primer layer, is treated in a low-viscosity polymer composition. Application of primer and protective layers is carried out with a layer of a repair mortar with thickness of 15-20 mm on the basis of a mixture of portland cement, sifted sand with grain size of up to 5 mm and acrylate.EFFECT: improved manufacturability of repair works and provision of structure protection against aggressive effect of environment after its repair.5 cl |
