The article presents the results of research on determination of rheological and strength characteristics of polymer mortars, based on carbamide resins. The models have been obtained, reflecting rheological and strengths properties of the material. The optimal compositions have been determined for performance of reconstruction works of concrete-based hydro-technical transport structures.

In the article the basic research results of adhesion processes of modified polymeric compositions with the recovered architectural elements of buildings are presented. The processes taking place in the contact area of polymeric solution with the repaired surface are shown; the influence of the repaired surface state on strength of adhesion with the polymeric solution is studied.

The article presents results of studies of epoxy-based polymeric composition of for repair and protection of concrete and reinforced-concrete facilities. Models have been designed, reflecting physical, mechanical and rheological properties of the composite. Analysis of the obtained results has been made.

The modification of polymer composition containing epoxide resin, amine hardener, alcohol-and-acetone solvent, and filler – dust of gas cleaning of ferrosilicium treatment – was performed. On the basis of analysis of experimental results the optimum compositions were chosen on the strength indices of polymer stone, in doing so the technological features of polymer mixture and cost of compositions were taken into account.
