| Popis: |
The purpose of this study was to evaluate the corrosion resistance of steel reinforcement in concrete samples containing modifying additives using an accelerated electrochemical corrosion method. It was found that the adhesion strength between the reinforcement and the cement stone of concrete largely depends on the corrosion resistance of the reinforcement in concrete. At the same time, the best result from the tested concretes was shown by the developed concrete of optimal composition, in which the adhesion strength between concrete and reinforcement is 1.7 times higher than that of control concrete without mineral additives. The obtained results can be explained by the fact that an increase in the density of concrete due to the modification of its structure with organo-mineral additives leads not only to an increase in its strength, but also to a better protection of steel reinforcement in concrete from corrosion. This will help to increase the durability of reinforced concrete structures of offshore hydraulic structures in Vietnam and increase the period of their maintenance-free operation. |
