Preventive and Protective Solution for Corrosion in Concrete through Chemistry

Damage caused by corrosion of concrete structure has been recognized as one of the major problem affecting service life of structure. But corrosion cannot be stopped compl-etely.It can be reduced if certain practices to combat corrosion are applied. Permeability is the gateway of corrosion. Hence corrosion - permeability interaction has been presented in this paper. Water proofing has been
suggested as preventive solution for concrete structure
exposed to corrosive environment . Structures are damaged due to corrosion in concrete.Suitable and effective
repair system is unavoidable protective solution for corrosion affected concrete structure. In the present paper the authors have made an attempt to present prev-entive and protective solution of corrosion in concrete through chemistry. Repair material, its criteria , various techniques and methodology has also been discussed. The
approach is also illustrated by presenting two case studies.
