Bonding of Recovery Concrete with Corrosion-Destroyed Reinforced Concrete Structure

. The adhesion of concrete is a decisive factor in restoring the performance reinforced structures. During operation an aggressive environment, agents penetrate through pores and capillaries to reinforcement which begins corrode. resulting corrosion products have large volume than metal itself, create pressure on protective layer from inside. Ultimately, it exfoliates, unprotected destroyed even more intensively, soon structure loses its bearing capacity. Standard restoration includes cleaning damaged surface, additional coating structure. However, after sometime, peeling repair often observed. This because by does not provide high-quality “old” “new” one. reason destruction surface influences. In most cases, carbon dioxide agent. study effect cement stone has shown crystalline framework material decrease cohesive strength. Micrographs undamaged corrosion, taken with magnification 7000 times, convincingly demonstrate results destructive work dioxide. significant grip. use forced heating mixture when placed contact restored leads appearance temperature gradients that enhance thermal diffusion. And greater gradient, intense deeper penetration dissolution into body being restored. this, turn, contributes impregnation liquid phase mixture. Crystallizing, form new stone, enhances strength binds intact structure, ensuring quality adhesion.
